1. Segment your audience

Segmentation is a powerful tool in your email marketing arsenal. Unfortunately, it is seriously underused by most brands.

If you want to impress your audience, you need to understand them better and create campaigns that appeal to them personally.

This is because each subscriber is an individual and they want to be treated as such.

The below email is obviously meant for men. Do you think women will be pleased to receive it?

If you don’t segment your audience first, you risk alienating a large proportion of them. And these are the folks who often unsubscribe from marketing emails or even mark your emails as spam.

By properly segmenting your list, you can tailor your messages to meet the specific needs of a specific group of subscribers.

If you’re not sure which segments to create in your ESP, here are a few to get you started (along with the type of emails you can send):

1. New Users: Welcome Emails

2. Personalize your campaigns

Personalized emails deliver 6X higher conversion rates compared to generic messages.

Connecting with subscribers at a more personal level is one of the most powerful email marketing best practices to improve audience engagement.

Some ways to include personalization in your email marketing campaigns:

  • Address them by their first name
  • Add their first name to the subject line
  • Provide user-specific data or a status report

3. Leverage the power of automation and triggered email marketing

Email marketing automation yields massive advantages by minimizing manual labor, saving time, and boosting efficiency.

You can create different kinds of automated campaigns for different purposes based on different behavioral “triggers”:

  • A person who buys an item gets notified of future sales in that category
  • Someone who subscribes to your  blog receives a welcome email or newsletter with a selection of popular articles or recommendations

  • A shopper who abandons their cart receives a reminder to complete their purchase

But automation does not have to mean generic! You can still send automated emails that are personalized and memorable. Try these tips:

  • Once you understand and segment your target audience, build customer “personas” and design emails for each persona
  • Target customer-centric keywords and optimize content for those keywords
  • Nail your subject line and headline
  • Create compelling copy

4. Create drip campaigns

Automated drip campaigns can also be very successful – if done right.

The idea is to send a series of emails over a period of time without spamming subscribers.

For a new subscriber, a drip campaign might look like this:

  • 1st (welcome) email: Send immediately on signing up
  • 2nd email: Promote certain products
  • 3rd email: Discount on selected products
  • 4th email: Upsell other products

You can create drip campaigns for all kinds of goals. Keep these tips in mind:

  • Always start by segmenting your audience
  • Define user personas
  • Personalize copy, images, offers, subject lines, etc.
  • Adjust send frequencies
  • Set up automation

5. Avoid using ‘No reply’ in the sender’s email address

The two things a person looks for when deciding whether – or not – to open an email are…

Subject line


From address

“No reply” in an email message (e.g. prevents recipients from responding to your emails. It also prevents them from opting out of further emails.

Not only is a non-branded sending address generic and impersonal (and super annoying), using No-reply also goes against CAN-SPAM – an important guideline for email marketers in the US. It protects the right of recipients to opt out of marketing emails.

Your subscribers are much more likely to open your emails if they know they were written by a human being for a human being.

6. Start a conversation…tell a story

Another way to “humanize” emails is to encourage conversations. A branded email address like is one way to do this. Encourage your subscribers to reply. You can also ask for feedback to build trust.

Another way is to weave storytelling into your emails. Stories can improve engagement, boost open and click-through rates, and even encourage more conversions.

The COVID-19 crisis has also opened opportunities for email marketers to show subscribers their “human” side and garner their trust. Here are some tips:

  • Use sensitive and empathetic “recognition” language that acknowledges the crisis
  • Avoid discount codes or promotional sales related to the crisis (“Special Corona discount!!”)
  • Help your subscribers navigate through this difficult crisis with personalized messaging

Do reinforce the human connection with your audience. Don’t overwhelm them with selfish-sounding brand messaging! For more tips on writing engaging emails, read here.

7. Craft intriguing subject lines

Personalized copy is very important.

But subject lines are important too – and this is an element that a lot of brands get really, really wrong.

A great subject line can convince a subscriber your email is worth opening while a below-par subject line will be ignored.

Invest time in crafting an intriguing subject line. Make it interesting and unique. Limit the length to 70 characters or less. Don’t be afraid to experiment with emojis, especially if the email theme is fun or light-hearted.

Research finds that using emojis in the subject line can increase open rates by 4.2%.

Incentives can increase open rates by as much as 50%.

You can also include incentives in your subject line to tempt subscribers to open your emails.

  • “Free shipping on orders of $50 and above”
  • “Receive a free Tee with purchases over $200”
  • “Buy in-store and get 20% off on your next purchase”

But be careful not to overwhelm your readers with savings-, offers- or product-related emails. And make sure that any incentives in the subject line are backed by warm, human-sounding copy in the email body.

8. Experiment with send times

Is there a “best” time to send marketing emails? A particular time of the day (or a particular day of the week) when your emails are most likely to be opened?

If you Google this question, you’ll probably find something like:

Tuesdays 10 AM


Thursdays 11.30 AM

The problem with such “prevailing advice” is that everyone takes it as gospel and follows it religiously. This means the crowd of email marketers all move to Tuesdays 10 AM or Thursdays 11.30 AM. And you are part of this crowd!

Every day, the average office worker receives about 120 emails.

How likely is it that yours will be one of the emails they actually read?

Fact: there’s no one best time or day to send emails to everyone. Find the best (or most optimal) time for each subscriber and email them accordingly.

Some ESPs include features to help you optimize send times based on audience segments, or even based on individual subscribers. Some also provide a “throttle” functionality so you can spread out email sends, and ensure that subscribers are not overwhelmed by your messages.

9. Make it easy to subscribe…and to unsubscribe

Your audience is busy. So if you want them to connect with your emails and newsletters, you must make it easy for them to subscribe. It’s also important to show them the value of subscribing by clarifying their question about “What’s In It For Me” (WIIFM).

Ask yourself: what will my subscribers get out of my emails?

  • Useful content?
  • Relevant offers?
  • Solutions to certain problems?
  • A good laugh

There’s no right or wrong answer here. The key is to focus on your audience, adjust your brand messaging, and design your emails accordingly.

Try these ideas to get more email signups:

  • Include (realistic) incentives
  • Give a sneak peak to interesting content, e.g. your company’s blog
  • Add a newsletter sign-up link to each blog post
  • Add sign-up options to your social media accounts and eCommerce store checkout page
  • Run a contest or giveaway for first-time subscribers (or purchasers)

Similarly, it’s also important to make it easy to unsubscribe.


Of course, you don’t want to lose subscribers, but if someone has made the decision to leave, making it harder for them will just annoy them even more. So, unsubscribe links in tiny fonts or low-contrast colors are not advisable because they can generate spam reports, which will affect your email deliverability.

Research shows that the best place to add your unsubscribe button is right next to your email address (which is not No-reply, remember?!). You can also add it at the end of your email.

10. Use incentives wisely

Earlier, we spoke about adding incentives to subject lines to tempt subscribers to open your emails.

Incentives inside body copy are a great way to (gently) push subscribers down the sales funnel.

Email Best Practices to Use Incentives

  • Include a clear, unambiguous CTA. Make sure it shows above the fold
  • Use words like “limited offer” and “offer valid till…” to create urgency and guide the user towards a particular action (without seeming pushy)

  • Include a ‘countdown timer’

A countdown timer is an animated clock that counts down to an important deadline, such as the end of a promotion, time left to renew a subscription, etc. It helps build excitement and create a sense of urgency while encouraging the subscriber towards taking an action. The email messaging can be personalized based on the event, or for an individual subscriber.

Incentives are also a powerful way to win back lapsed or disengaged customers, which we will cover later.

11. Use a double opt-in

This is why it’s important to clearly communicate to recipients that they’re subscribing to an email list. Provide opt-in checkboxes. You can also include a “double opt-in” so a person has to confirm their subscription in one email to receive further emails.

Most people hate unsolicited email, so adding them to your email list without their explicit consent or confirmation is a sure-fire path to unsubscribes and even spam complaints.

This extra step verifies your subscriber’s email address and tells you that the person wants to receive emails from you.

Although the double opt-in will add an extra step to your subscriber’s journey, it is still one of the safest email marketing best practices around!

12. Maintain list hygiene

It’s great to have a long list of email subscribers.

But if most of them never engage with your emails or take any actions, all they’re doing is eating up your resources. They may even hurt your overall deliverability statistics.

Too many bounces and invalid email addresses can also hurt your campaign deliverability and overall success.

That’s why it’s essential to clean your subscriber list regularly. Here are some proven tips:

  • Remove all “hard” bounces caused by invalid, non-existent or closed email addresses.
  • Monitor “soft” bounces. A soft bounce can be caused by a full mailbox, an inactive account or a temporary domain failure, and is often temporary. But if you consistently get a soft bounce from an email address, remove it from your mailing list.

Your ESP may have a “review bounced emails” feature. Check these numbers and then decide what action to take next.

Another thing you can do to clean up your mailing list is to remove disengaged email addresses. This can be a tricky proposition. Shouldn’t you give such subscribers another chance to “come back”? The next email best practice will address this very question. However, if a subscriber has not opened any of your emails for a year or more, you can assume that they’re no longer interested in your emails, so you can remove them.

Adding a double opt-in to your emails (covered earlier) is also a good way to maintain list hygiene.

13. Focus on dis-engaged customers and cart abandoners

The bane of every email marketer – disengaged customers and cart abandoners!

What should you do about such people? Keep in mind that they are two different categories of people, so you should have different strategies to deal with them.

Disengaged customers are a big part of your email list. Working on this list can improve its quality, reduce subscriber churn, improve your domain health and even convert your email subscribers into leads. And that’s why, you need to make an effort to re-engage them for as long as you can. Here’s where “re-engagement emails” can really do the trick.

Once you identify inactive subscribers, here are 4 types of re-engagement emails you can send to bring them back on-board:

  • Polls and surveys: Ask them to complete a poll or survey, and send them a free gift or promo code when they do so
  • Competition: Use contests or giveaways to generate interest in your campaign
  • Coupon or promo code: Send a special promo code or coupon with a message reminding them that it’s been a while since they engaged with your emails
  • New product recommendations: Include personalized product recommendations based on their purchase history or demographics

Source: Really Good Emails

In every email, make sure that you:

  • Remind them of the benefits of being a subscriber
  • Make the interaction personal
  • Humanize your brand

When designing your re-engagement email campaign, follow these strategies:

  • Address their spam complaints
  • If you’re using SFMC, create an automated process with Process Builder to automatically to email inactive/dis-engaged subscribers
  • Use templates and tailor them to your needs (or type of re-engagement email)
  • Include personalized content
  • Optimize your emails for mobile

What about cart abandoners?

An abandoned cart represents a potential sale that didn’t convert into an actual sale. In effect, it represents a wasted opportunity.

To minimize abandoned carts and convert them into completed purchases, you can send these almost-customers abandoned cart emails.

Abandoned cart emails generate the highest average revenue per click at $36.02. They also generate the second-highest revenue per open at $1.77.

Depending on who the customer is, and when they abandoned you (before cart checkout or during browse checkout), you can send abandoned cart emails with different kinds of messaging, such as:

  • Still thinking about it?
  • Need more time to decide?
  • Tell us how we can help
  • Here’s what you’re missing
  • We miss you. Come back!


You can also send different kinds of abandoned cart emails like:

  • Email with products they added to their cart (but didn’t purchase)
  • Email with similar, recommended products
  • Abandonment surveys
  • Special (or limited time) offers
  • Contact form with or without callback button

Source: Really Good Emails

To reduce cart abandonment, here are some tricks you can try:

  • Send a series of messages instead of just one single email: 2-3 is a good number
  • Along with names, also include product pictures and recommendations
  • Add seasonal context to your emails, such as upcoming holidays, the shopper’s birthday, anniversary, etc.
  • Create a sense of urgency with discounts, promo codes or limited time offers
  • Make sure your abandonment cart emails are triggered quickly – ideally 24 hours within abandonment

14. A/B test your email campaigns

Before sending out an email, test it on a small group within your target audience. This will help you make any necessary changes before sending out the final version, and thus increase your chances of success.

Most ESPs, including Salesforce Marketing Cloud, allow you to A/B test multiple elements of your campaign. These include:

  • Subject line
  • From name
  • Content areas
  • Images/visuals
  • Personalization
  • CTA text
  • Send time
  • Pre-header

Here are a few tips to run a successful A/B test for your email campaign:

  • Define a hypothesis and goal. What do you hope to achieve with A/B testing?
  • For more accurate results, Choose the largest sample you can
  • Choose the same sample sizes for both versions
  • Test as early as possible and only one variable at a time
  • Wait at least 24 hours before declaring a version as the winner’

15. Reward loyal subscribers

Your loyal subscribers should be a focus area for your email marketing efforts.

They choose to stay subscribed to your mailing list. They may also buy from you and not from your competitor.

That’s why rewarding them for their loyalty with special offers, discounts, or “freebies” is absolutely essential. This will not only reinforce their “specialness” but also make them feel valued. This means that they will stay with you and not go anywhere!

Bonus – your open and click rates could also increase!

16. Implement clear, unambiguous CTAs

Your email marketing strategy is perfect.

Your copy is personalized, human and compelling.

Your graphics are attractive.

You chose the right templates and optimized them for mobile.

What about a Call to Action (CTA)?

Here’s where your email campaign stumbled. A CTA is either missing in your emails, or it’s messaging is not clear.

Your email campaign has a specific goal and one way to meet it is to include clear CTA copy plus a button or link.

Research has proven that CTA text can increase conversions by pushing readers towards a specific action and by giving them the choice to do so.

Here are some useful tips to optimize your CTA text and button (or link):

  • Be specific with your CTA copy
  • Don’t be ambiguous with the button
  • Customize the text according to the action you want the reader to take
  • Use contrasting colors for the button so it stands out, but stay within the parameters of your brand’s colors and designs
  • Focus on the benefits to the reader
  • Optimize CTA for mobile

17. Don’t be a spammer!

Every brand wants more opt-ins, more subscribers, more conversions and more sales.

But bombarding people with multiple emails is not the way to go about achieving these goals.

In this case, more is not merrier.

When you send too many emails, your engagement rates will fall, and unsubscribe rates and spam complaints will likely go up.

But how can you find that tipping point between too many and too few?

As with “ideal send times”, there is no “ideal number of emails”.

Experimentation is the only way to arrive at an optimal number.

But there are other things you can also do to keep spam complaints down:

  • Make sure your content is relevant and as far as possible, personalized
  • Never buy an email list. Purchased lists tend to generate very high unsubscribe and spam rates
  • Add your brand’s physical address somewhere in the email, say at the end
  • Give people an easy way to unsubscribe
  • Avoid using ‘No reply’ in the sender’s email address
  • Break down your content into smaller, more easily consumable chunks, ideally each with its own headline and/or image to keep your email out of spam scanners

It’s also important to remove common spammy words from content. Examples include $$$, Earn $, hardcore, and make $. If you’re using SFMC as your ESP, check out Content Detective in Email Studio to review and remove spammy words

18. Create mobile-optimized emails

In 2019, mobile was the most popular reading environment, accounting for 42% of all email opens. 

Studies have found that 69% of mobile users delete emails that aren’t optimized for their device.

If your email campaigns are not mobile-optimized, you’re missing out on a huge opportunity for greater conversions, engagement and even sales.

Tips to create mobile-ready email templates:

  • Test the links. Broken links are a strict no-no
  • Make sure images load properly
  • Text should be readable and not cluttered; include white space

  • Scrolling and navigation should be easy; keep the length short
  • Stick to a single column layout

  • Use short subject lines: 25-30 characters maximum
  • Use pre-header text to entice readers to open the email
  • Modify your copy to ensure that it fits well on a mobile device’s screen
  • Show CTA text clearly and above the fold
  • Create browser-agnostic emails

19. Add ALT text to images and buttons

Adding ALT text to emails helps users understand what they’re reading, even if the HTML doesn’t render properly, or if their email client blocks images by default. They can take the action you want to take and understand where to click.

Without ALT text, they will simply see a blank space where a button or image is supposed to be.

Make sure you add ALT text to every image and button in every email. If you have created landing pages, hyperlink this text to these pages.

20. Track, Review, Analyze, Repeat

Email marketing is not a one-time-only, set-it-and-forget it effort. Once you send an email or finish a campaign, you should review its performance and compare it against your KPIs.

At the least, you should analyze these statistics for a campaign:

You can also analyze individual emails for a more granular view of their performance. For example, which CTA button performed better? Which content chunk was clicked on more? Did buttons do well or did text links?

This information can help you adjust your email marketing strategy, design, copy, or layout.

You should also compare the performance of your campaigns against industry benchmarks.

In particular, SFMC Email Studio provides a number of key metrics to help you track campaign performance. Use the tracking reports to dig deeper into the data, to identify the best- and worst-performing campaigns, and to improve audience segmentation.


Email marketing can be overwhelming for the under-prepared or under-informed. We’ve covered a lot of practical information in this guide to help you prepare and be better-informed. Now you have no reason not to design kick-ass email marketing campaigns that your audience will want to read!
