AMP in Email: Everything you need to know about it

[This blog was originally posted on April 19, 2019 and has been updated to showcase new examples]

Google launched the Accelerated Mobile Pages (AMP) Project on 7th October 2015 as an open-source technology that was designed to enhance the website performance and user experience on every device regardless of the screen size. It is a framework of HTML, CSS, and JS with speed and performance optimization.

Gmail holds the credit of being the first email client to offer AMP for email support and the incorporation of dynamic and interactive elements in email. 

How AMP for email Works?

AMP is a powerful technology that drastically enhances the subscriber experience. Gmail makes use of a separate MIME-type for the AMP version of the email: text-x-amphtml. Developers are familiar with the usage of MIME in email as it has been used to package plain-text versions of the email and HTML versions too. You will need to have a third MIME-type in your email if you want AMP-powered emails to work in Gmail.

With the execution of this technology, the user experience improves significantly for Gmail users.

Using G Suite for AMP

G Suite has introduced a beta program for fast-loading dynamic email in Gmail, that enables email senders to embed AMP into the messages. This makes the emails more actionable by including updated information in them.

Important Points To Consider While Using AMP HTML Email

  1. You should get whitelisted with Gmail to send AMP email and send the email through supported ESPs only.
  2. You cannot copy your HTML code and paste it and add a bit of AMP code to it.
  3. Follow strict validation rules.
  4. Avoid using any inline styles.
  5. Have only 1 <style amp-custom> block.
  6. Make sure you adhere to the 50,000 characters limit of CSS.
  7. Use <amp-img> rather than <img>.
  8. CSS Support

Advantages of AMP in Email

AMP Email Examples

1. With AMP, Pinterest created an awesome email that allows the user to manage the subscription right in the email.

2. EmailMonks (now Email Uplers) had been trying to implement AMP for quite some time and we finally created a nice AMP email.

Applications of AMP

AMP is a great idea for businesses who are looking forward to generating a greater ROI and driving business growth.

Here’s how you can incorporate AMP in your email marketing strategy.

1. Ecommerce

Ecommerce email marketers can use AMP to offer a complete checkout option within the email itself. Subscribers or users can directly make the purchase from this email with an option to select the variation like color/size/quantity and complete the checkout process (except the payment processing) without landing on a webpage. Integrating AMP in cart abandonment emails will work in a similar fashion.

2. Finance

For the Finance industry, AMP for email can be beneficial if we provide them a form within an email to calculate the loan details by just filling up the loan amount and loan duration. It can also enable several other financial calculations in the email itself.

3. Travel and Food Industry

AMP email can be beneficial for travel industry email marketers by letting the subscriber check the availability of the tickets and book the same from the email itself. This idea can also be implemented for booking a movie ticket or booking a table at a restaurant.

4. Goods and freight

Marketers in goods and freight industry can send AMP emails so that their subscribers can easily track their courier. It takes the customer experience to a whole new level.

5. Event Invitations

Marketers can send event invites with AMP so that the recipients can RSVP directly through the email. This will generate better engagement with the emails and get you more attendees. You can use the same strategy to yield more registrations for your webinar.

6. Survey Emails

AMP would make survey emails more effective by allowing the readers to respond right in the email. With AMP, the user would not have to go to the landing page to give their feedback. The smooth experience will enhance the response rate for any survey.

Limitations of AMP Email

1. It is a new language to learn.

Despite the fact that it is an open-source technology that anyone can use, people will hesitate to use it – primarily because it is a technique-sensitive technology and it has exclusive pre-requisites that need to be fulfilled.

2. ESPs And Other Tools Do Not Offer AMP for Email Support.

Email marketers have to use two different MIME types for creating emails for the HTML part (text/html) and plain-text version. Therefore, every email should have an HTML version and a plain-text version in the ESP. When it comes to AMP email, a third MIME-type will be needed. This adds to the complexities of executing AMO. If ESPs do not add support to this third MIME-type, it is not possible to create or deploy AMP-powered emails.

As far as Gmail is concerned, it has several rendering issues like discrepancy in email display for accounts working on Gmail addresses and non-Gmail addresses that use POP/IMAP.

3. Email performance tracking is a challenge.

It is important to measure the performance of your email campaigns. With AMP-powered emails, it is a challenge to track the email metrics. The interactivity in these emails, like hover-based events or clicking through a range of different deals cannot be measured with conventional email metrics.

4. Emails can be updated post-deployment.

As the content of AMP emails can be updated even after hitting the Send button, it could leave the subscriber confused. It is tough to imagine an email that changes each time you open it. It might lead to trust issues if the subscriber is not aware of this new technology.

5. It is time-consuming.

As it is far away from the standard coding practices, it needs proper expertise and can get time-consuming. Email developers will have to learn a specific skill set just to create an email – that is quite daunting. As far as Gmail is concerned, it has several rendering issues like discrepancy in email display for accounts working on Gmail addresses and non-Gmail addresses that use POP/IMAP.

Compatibility of AMP

Future of AMP

As it is an open source technology, it is more likely to get supported by other email clients too. ESPs do not support the third MIME type as of now. They would need to add special functionality to their platforms to support AMP. In the days to come,, Yahoo!, and will extend support to AMP emails.

We look forward to receiving some awesome AMP email in our inbox by brands like, Pinterest, Doodle, etc.
