Auto Inject Opt-Out Links

Stay compliant and save time—drop [[notifiedby:unsubscribe]] in your email and we handle the rest.

Dealing with opt-outs is a legal and deliverability must-have. With NotifiedBy, you don't need to build or manage opt-out logic yourself:

Automatic compliance.
Add [[notifiedby:unsubscribe]] to your email or your master template and we generate a working, per-recipient unsubscribe link—no opt-out code of your own.
You choose where it goes.
The link lands exactly where you put the placeholder, styled by your own template.
One-click unsubscribe.
We add the RFC 8058 List-Unsubscribe headers, so Gmail and Outlook show their own unsubscribe button too.
Instant suppression.
Once someone unsubscribes, we block further emails—no risk of accidental future sends.
Webhook integration.
Supply a webhook URL and we'll notify your app of every unsubscribe, so you can sync your own user records.

A clear unsubscribe option, sitting wherever your design calls for it.

Put [[notifiedby:unsubscribe]] wherever you want the link—in an email body you send through the API, in a flow template, or once in your master email template so it appears on everything.
We swap it for a real link at send time, unique to that recipient, and add the one-click unsubscribe headers.
Add an optional webhook URL in your Sender Settings to be told about every opt-out.
Recipient clicks unsubscribe:
– They're instantly suppressed from future sends
– We fire your webhook (if set), so you can update your own database.
No further emails are sent to unsubscribed addresses via NotifiedBy—guaranteed.

Where does the unsubscribe link appear?
Wherever you put the [[notifiedby:unsubscribe]] placeholder—it inherits the styling of the surrounding template. Emails without the placeholder are left untouched.
What happens when a user unsubscribes?
We blacklist that address immediately. No more emails are delivered to them from your account.
How does the webhook help?
We POST every unsubscribe event to your webhook URL, so you can keep your own user tables up to date.
What if I email unsubscribed users by mistake?
No worries—NotifiedBy blocks those sends automatically, protecting both you and the recipient.

Hassle-free unsubscribe management and always-on compliance—built right in.
