Connect SendGrid

Sends email and adds marketing contacts through your SendGrid account.

Updated 2026-11-02

01What it does

  • Rules: send an email
  • Rules: add a marketing contact

02What you need

  • API key — kept encrypted, never shown again. Settings → API Keys → Create API Key.

03Connect it

  1. In SendGrid, finish Sender Authentication (Settings → Sender Authentication) for your domain or a single sender.
  2. Open Settings → API Keys → Create API Key. Full Access is simplest; a Restricted key needs Mail Send and Marketing.
  3. In your site → Manage → Integrations, choose SendGrid, paste the key (starts SG.) and press Connect.
  4. Open the Rules tab in your site → Manage → Integrations, choose an event (e.g. "Form submitted") and pick an action from this tool. The fields are pre-filled from the form; glance, then save.

04Check it works

  • The card shows Working.
  • Submit your own site's form once, then open the tool's run log (the clock icon on its card): a green row with a 2xx status means the other side accepted it.
  • New contacts can take a few minutes to appear in Marketing → Contacts.

05If it does not work

  • 403 on send — The From address is not an authenticated sender in SendGrid.
