Works with SendGrid
Email marketing on your SendGrid account.
SendGrid is the household name in developer email, with infrastructure trusted at enormous scale. GoodPostal adds the email marketing layer, so you can design and send newsletters with SendGrid instead of building against its APIs.
What GoodPostal adds on top of SendGrid
Signed event webhooks, set up for you
GoodPostal registers the SendGrid event webhook with your consent and verifies its cryptographic signature on every event before trusting it.
Quota awareness and overage protection
GoodPostal watches your SendGrid plan volume and applies your chosen at-limit behavior: pause the campaign or keep sending. No surprise overage.
Campaign tooling SendGrid does not include
A visual editor, contact groups, scheduling, and analytics that survive a provider switch, without SendGrid Marketing Campaigns pricing.
Suppression sync
Bounces and spam complaints reported by SendGrid automatically suppress contacts in your workspace.
SendGrid details, handled
- SendGrid cryptographically signs each webhook; GoodPostal handles key management and verification automatically.
