AMP (Accelerated Mobile Pages) Email

What is AMP email? 

AMP (Accelerated Mobile Pages) is an open-source web framework originally developed by Google to create fast, lightweight, and secure web experiences. While AMP is widely known for webpages, it also powers AMP for Email, enabling interactive, dynamic content inside email inboxes. AMP for Email allows businesses to embed interactive, action-driven workflows directly inside emails, reducing the need for recipients to leave their inbox to perform actions. In the email ecosystem, AMP transforms emails from static messages into actionable interfaces.

AMP in the context of email  

AMP for Email is a specification that allows senders to include AMP-powered content inside emails. Users can interact with emails (e.g., forms, carousels, accordions, live data) without leaving their inbox.

In traditional email, content is limited to:

  • Static HTML.

  • Links that redirect users to external pages.

  • Basic CSS with strict restrictions.

AMP extends this by allowing:

  • User actions (submit, select, expand).

  • Live data rendering at open time.

  • Dynamic UI components.

  • Backend-powered interactions.

All of this happens inside the inbox, without requiring users to open a browser or log into an app.

How AMP emails actually work  

An AMP email isn’t sent as a single format. Instead, it’s delivered as a MIME multipart email, which includes:

  • A plain-text version.

  • A traditional HTML version.

  • An AMPHTML version.

The inbox automatically displays the best-supported version. If AMP isn’t supported, the user sees the HTML fallback—ensuring compatibility across all devices.

What is AMPHTML?

AMPHTML is the language of AMP emails and is a restricted version of HTML designed specifically for safety and performance. AMPHTML uses predefined AMP components to make the email interactive and requires strict validation to prevent abuse.

What makes AMP emails interactive?  

The defining feature of AMP emails is inbox interactivity and enabling users to engage with content directly inside the email.

This is made possible using AMP components, such as:

  • amp-form for form submissions.

  • amp-carousel for image or product sliders.

  • amp-accordion for expandable sections.

  • amp-list for dynamic content pulled from APIs.

Together, these components turn emails into mini web apps inside the inbox. Traditional emails freeze the moment they’re sent. AMP emails, however, can fetch fresh data at the moment the email is opened.

This enables use cases like:

  • Live order or delivery status.

  • Updated appointment availability.

  • Real-time pricing or inventory.

  • Personalized recommendations.

Every open can show something new—without having to resend the email.

AMP email components   

AMP form (amp-form)  

amp-form allows users to submit forms directly from the email, such as:

  • RSVPs

  • Surveys

  • Feedback

  • Lead capture

AMP list (amp-list)  

amp-list fetches and displays live data at open time, enabling:

  • Order status updates

  • Ticket availability

  • Live pricing

  • Delivery tracking

This is especially important for transactional emails that carry information about an action performed. AMP list helps provide live data in the transactional email.

AMP carousel (amp-carousel)  

A carousel component that users can swipe through. This component is used to display:

  • Product galleries

  • Offers

  • Image sliders

  • Feature highlights

AMP accordion (amp-accordion)  

Used to show collapsible sections that users can expand if and when required. These are ideal for:

  • FAQs

  • Order summaries

  • Policy details

  • Multi-step information

AMP selector (amp-selector)  

Enables the selection of options within the email, such as:

  • Polls

  • Ratings

  • Preferences

  • Multiple-choice inputs

Authentication requirements for AMP emails  

To send AMP emails, domains must meet strict authentication standards, including:

  • SPF

  • DKIM

  • DMARC

  • Domain approval or whitelisting

These safeguards ensure that AMP emails can’t be exploited for phishing or spoofing.  

Real-world use cases for AMP emails  

AMP emails shine in scenarios where immediacy and interaction matter:

  • Order tracking and delivery notifications

  • Appointment scheduling and rescheduling

  • Event invitations and confirmations

  • Product browsing and recommendations

  • Customer feedback and surveys

These experiences feel faster, smoother, and more intuitive.

AMP email best practices for businesses

  • Use AMP only for high-intent emails. Not every SaaS email needs AMP. AMP works best where users already have clear intent and will benefit from speed.

  • Always include robust HTML fallback in case the recipient’s inbox doesn’t support AMP emails. Dynamic design shouldn’t be at the cost of accessibility.

  • Restrict actions to low-risk operations and aim to focus on a singular action or interaction inside the inbox instead of overloading the email with AMP components.

  • Implement AMP for your emails gradually and in a phased manner. During the implementation, monitor abuse and rate limits to iterate the email as you see fit.

  • Align AMP emails with product analytics. Monitor analytics like action completion rate (not just clicks), time-to-action, drop-off between AMP and HTML users and impact on product activation or retention to review AMP success.
