Overview
Developer-first transactional email with React Email integration. Resend handles transactional or marketing email, sending, deliverability, templates, and reputation.
What you get
Tools in this category provide SMTP/REST APIs, template editors, suppression lists, bounce/complaint handling, dedicated IPs, deliverability dashboards, and increasingly AI-assisted copy and audience tools. Marketing-focused products add segmentation, broadcasts, and automations on top.
Where it fits in your stack
They sit between your app server and your users’ inboxes. Most teams keep a transactional sender (receipts, password resets) separate from the marketing sender (newsletters, lifecycle), partly to protect deliverability and partly to keep ownership clean.
Who it’s for
Resend is aimed primarily at builders looking for a focused tool in this space. When evaluating, look at deliverability data, dedicated-IP options, regional sending, suppression handling, the quality of templates and editor, and the pricing curve at your real send volumes.
Pricing & licensing
Email providers usually price by sends per month, with free starter tiers, paid scale plans, and add-ons for dedicated IPs and advanced deliverability tooling. Check Resend’s site for current quotas, and remember that monthly active recipients matter more than headline send volume on most marketing-focused plans.
