312 reviews
Free tierHas API
SendGrid is the proven enterprise choice for email delivery at scale. The infrastructure handles billions of emails reliably. The DX is showing its age compared to Resend, but the reliability and scale are unmatched. For applications sending serious email volume, it remains the safe choice.
What's great
- Battle-tested infrastructure for high-volume email delivery
- Combined transactional and marketing email in one platform
- Strong deliverability with dedicated IP options
Watch out for
- Developer experience feels dated compared to Resend
- Pricing complexity with multiple plans and add-ons
- Twilio acquisition has not improved the product significantly
