Stay free if you only need basic features. Upgrade if you need advanced features. Most solo builders can start free.
Resend wins on developer experience — cleaner API, better documentation, React email template support, and a modern dashboard. SendGrid wins on scale, deliverability infrastructure, and feature completeness. For new projects focused on developer experience, Resend is better. For high-volume production email with advanced deliverability needs, SendGrid is safer.
Yes, SendGrid offers 100 emails/day on the free plan with no expiration. This includes API access, basic analytics, and the event webhook. For development and small-scale production, this is sufficient. No credit card required for signup.
Yes, through the Inbound Parse Webhook. Configure your DNS to route emails to SendGrid, and it forwards parsed email content to your application. This enables agents that respond to incoming emails, though the feature is less polished than dedicated email receiving services.
On dedicated IPs with proper domain authentication, 95-99% inbox placement is typical. On shared IPs (lower plans), rates can be lower and variable depending on other senders sharing the IP. Proper SPF, DKIM, and DMARC configuration is essential regardless of plan.
Start with the free plan — upgrade when you need more.
