Frequently Asked Questions
Is Resend a good replacement for SendGrid?
For transactional email with modern developer experience, yes. For marketing automation and visual drip builders, SendGrid still offers more built-in features. Resend is catching up quickly but requires more custom code for drip campaigns.
Can I build drip campaigns with Resend?
Yes, but the drip logic must be built in your application code. Resend provides the sending API and React Email templates, but has no built-in automation builder or sequence management.
Which has better deliverability?
SendGrid has a longer track record and more mature infrastructure. Resend (built on AWS SES) is competitive but newer. Both achieve 90%+ inbox placement with proper authentication setup.
Does Resend support React Email?
Yes. Resend is built by the same team behind React Email and offers native support for building emails as React components with full TypeScript safety.
Which is better for SaaS drip emails?
Neither is purpose-built for SaaS. Resend excels at developer experience, SendGrid at automation. For SaaS-specific drip with billing triggers, Sequenzy is the most targeted option.
