Can SES Mailbox handle SaaS onboarding emails?

Yes. SES Mailbox supports campaign scheduling, dynamic segments by user attributes, and REST API for triggering emails programmatically — ideal for trial onboarding, feature announcements, and retention campaigns on AWS SES.

Does SES Mailbox support transactional and marketing email together?

SES Mailbox focuses on marketing and lifecycle email campaigns. Transactional emails (password resets, receipts) are better sent directly via AWS SES API or SES SMTP. Both can share the same AWS SES account.

For SaaS & product teams

Lifecycle email + transactional,
on one bill.

Stop paying SendGrid for transactional and Customer.io for lifecycle. SES Mailbox does both — through your own AWS SES account — for $9.99/mo + cents per thousand sends.
