Migrate to Anypost

Moving providers is mostly mechanical: swap the SDK, point your auth at an Anypost key, and reshape a request body or two. These guides walk through each switch provider by provider, with before-and-after code for every SDK and a full webhook event-name mapping.

You can run your current provider and Anypost in parallel during cutover; they are fully independent. Migrate one email type at a time and verify delivery before cutting over completely.

From Amazon SES

Drop the AWS SDK, IAM, and SNS: one API key, a flat send body, and direct HTTP webhooks.

From Mailgun

Swap Basic auth + form-encoded requests for a Bearer token and JSON.

From Postmark

Rename PascalCase fields to camelCase, swap the auth header, and turn To into an array.

From Resend

A light migration: change the package and key, then flatten tags and adjust your webhook loop.

From SendGrid

Flatten the personalizations wrapper into a plain JSON body and remap webhook event names.

From SparkPost (Bird)

Now Bird Email: switch to standard Bearer auth, flatten the nested body, and remap webhook events.
