What is the difference between SendGrid and SES Mailbox for marketing email?

SendGrid is primarily a transactional email API; its marketing features cost $249/mo extra. SES Mailbox is built marketing-first — campaigns, subscriber management, segments, and analytics on your own AWS SES infrastructure.

How much does SendGrid marketing cost vs SES Mailbox?

SendGrid Marketing Campaigns starts at $249/mo. SES Mailbox Pro is $9.99/mo flat plus AWS SES at $0.10 per 1,000 emails — roughly $15/mo at 50k contacts. That is 94% less per month.

The SendGrid alternative for marketers

SendGrid is built
for developers.

It's a great transactional API. But Marketing Campaigns is a $249/mo bolt-on that still routes through SendGrid's shared infrastructure. SES Mailbox is the opposite: built marketing-first, sends through your own AWS SES.
