Sidemail

Send transactional emails, newsletters, and automated sequences for software products

Meet Sidemail

Sidemail is an email platform for software products that combines transactional delivery, newsletters, contact profiles, and automation. Developers can send password resets, welcome messages, and other application emails through an API, using templates, Markdown, plain text, or custom HTML. Scheduled delivery and attachments are also supported.

A visual template editor handles branding and responsive layouts, while the dashboard helps teams manage and analyze sending across projects. Contact records can be imported from Stripe and used in automated email sequences. Sidemail is useful for product teams that want application messages and customer communication in one service, with both developer integrations and tools for managing content.
