SendStreak

SendStreak is a BYOS (bring-your-own-server) email platform: you connect the email backend you already trust - AWS SES, Gmail, Postmark, or any bare-bones SMTP server - and SendStreak adds the tooling of a full email platform on top: visual templates, event-triggered automations, retries, routing across backends, and unified analytics. Teams get feature parity with platforms like Mailchimp or Customer.io while keeping their own infrastructure and sender reputation. Pricing is flat pay-as-you-go, per email sent - never by audience size.
