Add to an audience in Mailchimp when an email bounces in SendGrid
When an email bounces in SendGrid, add to an audience in Mailchimp.
Start the 14-day trial, then find it under Templates → Library. It installs into the client you choose, switched off, with its checklist.
Every step, in order
When it happens in the first app, the step runs in the second, with the client’s own account.
- An email bounces
- An email bounced, within seconds. The API key needs Event Webhook access (Mail Send alone cannot make one), and each trigger uses one of the plan’s event webhooks.
- Add to an audience
- Adds the email to an audience, or updates its merge fields if it is already there: a lead who submits twice is one subscriber. The status applies to a new subscriber only; an existing one keeps theirs (change it with “Update a subscriber”).

What each client fills in
- Mailchimp: Audience ID
- For example Audience → Settings → Audience name and defaults
The accounts it needs
Each is the client’s own, stored encrypted and never copied between clients. Until one is added the client’s checklist shows it, and nothing runs.
SendGrid → Settings → API Keys → Create API Key with Mail Send access; for the triggers, also the Event Webhook settings permission (user.webhooks.event.settings.read and user.webhooks.event.settings.update), or Full Access. The From address must be a verified sender.
In the client’s Mailchimp: Profile → Extras → API keys → Create A Key. The server prefix is the part after the dash (us21).
After you install it
It lands switched off. The client’s checklist holds exactly this:
- Connect the client’s SendGrid, for “An email bounces”
- Connect the client’s Mailchimp, for “Add to an audience”
- Fill in Mailchimp: Audience ID (For example Audience → Settings → Audience name and defaults)
