Smart. Focused. Email.
Fast, cross-platform email designed to filter out the noise - so you can focus on what's important.
Definition
💡 SMTP server: The system responsible for sending your outgoing email. When you hit Send, your email goes to an SMTP server first. It processes the message, figures out where it needs to go, and relays it to the recipient's mail server. SMTP is the sending half of email. Receiving is handled by IMAP or POP3. The protocol is defined in RFC 5321.
What dynamic email actually changes
Regular email is static by design. Open a message from three days ago, and it says exactly what it said the day it arrived. That's usually fine. But it also means every "check the latest status" or "see new comments" moment forces you out of your inbox and onto some separate webpage, just to get one small update.
Dynamic email closes that gap. Google Workspace's documentation describes it plainly: dynamic email lets you interact with a message the way you'd interact with a website, without leaving Gmail. A comment notification from a shared document can update in place every time someone replies. An event invite can let you RSVP directly, and the message updates to reflect your response.
For anyone managing a lot of email, the appeal isn't the novelty. It's the time saved. Fewer tab switches, fewer "let me go check the doc" detours. If you're the kind of person who treats your inbox as a place to track ongoing things (a shared document, a live thread, an approval request) dynamic email means you actually see the current state instead of a screenshot from whenever the email landed.
Dynamic email is really just the newest layer of email automation: the message itself keeps working after it's sent, instead of sitting there waiting for you to go do something else. Pair that with an AI email writer drafting the message in the first place, and the email is doing more of the work at both ends, before you send it and after.
How dynamic email works
Technically, dynamic email runs on a framework called AMP, short for Accelerated Mobile Pages. Google originally built AMP to speed up web pages on mobile. AMP for email borrows the same approach: a stripped-down, secure version of HTML and limited scripting that lets an email fetch new content or accept your input after delivery.
There's a real security tradeoff being managed here, which is why it's not just standard HTML with more features bolted on. Dynamic emails have to be sent from a verified, authenticated domain (with SPF, DKIM, and DMARC properly configured), and Gmail requires senders to register before their dynamic messages get treated as anything other than a regular static email. That vetting step exists because letting a message make live requests after it lands in your inbox is powerful, and power like that needs guardrails.
Right now, support is real but not universal. Gmail supports it natively. Some other providers have started adopting the AMP for email spec, but it's nowhere near as ubiquitous as plain HTML email. So senders still have to build a fallback static HTML email for anyone whose email client doesn't support the dynamic version.
Turning dynamic email on (or off)
You don't build dynamic email the way you draft a regular message. It's a sender-side feature, and turning it on (or off) as a recipient is mostly about one setting.
In Gmail: Dynamic email is on by default for most personal accounts. If you want to check or adjust it, go to Settings, then General, and look for the Dynamic Email section, where you can toggle developer settings for testing purposes.
In Outlook: Outlook doesn't currently offer a user-facing dynamic email toggle in the way Gmail does. Interactive content support varies by version and is evolving, so treat any dynamic-style behavior you see there as provider-specific rather than a standard feature.
Why dynamic email doesn't show up everywhere
Why don't I see dynamic content in every email I get?
Because support still isn't universal. Gmail handles it natively; plenty of other clients don't render it at all, which is why senders still build a plain fallback version.
Is dynamic email a bigger phishing risk?
It can be, since the same interactivity that makes it convenient also makes a convincing fake harder to spot. Verify the sender before you click or fill in anything inside a dynamic message.
Can I turn dynamic email off in Gmail?
Yes, through Settings, then General, in the Dynamic Email section. Most people leave it on, since it's opt-in at the sender level anyway.
Does Outlook support dynamic email the same way Gmail does?
Not with a standard, user-facing toggle. Support there is inconsistent and version-dependent, so don't expect the same experience across clients.
