Key differences between SendGrid and Postmark #
These are some important differences to be aware of when moving over to Postmark from SendGrid:
- Postmark does not allow anyone to send marketing or bulk email, whereas SendGrid does. If you were sending your marketing and/or bulk email through SendGrid and want to switch those over to another provider, we highly recommend using Campaign Monitor for any bulk email you need to send.
- Since Postmark does not allow bulk email (including subscription newsletters), there are no list management features available in Postmark, such as handling unsubscribes or adding unsubscribe links to your emails.
- Postmark’s APIs do not have XML support, all requests and responses will be in JSON.
- Postmark does not have a reseller program and there are no Reseller APIs available.
- Postmark uses a pay as you go credits model instead of subscriptions/plans. See our pricing page for more details. One credit is used per email sent/received and credits never expire.
- We do not recommend using dedicated IPs for most senders but do move senders to dedicated IPs at no additional charge once they reach a significantly large volume.
