SendGrid bundles transactional APIs, marketing campaigns, and deliverability tooling, often with annual commits. Reloop is API-first, Apache 2.0, and self-hostable, with campaigns and transactional sends in one codebase. Reloop Cloud Free is 6,000 emails/month (200/day).

Reloop is the email service / infrastructure (ESP + MTA). It is not a multi-ESP connector that sits on SendGrid, Mailgun, Resend, or SES.

## FAQ

### Is Reloop a good SendGrid alternative in 2026?

Yes, for teams that want a modern API-first platform without Twilio bundle pressure or annual commits. Reloop matches SendGrid on transactional API, marketing campaigns, template editor, SMTP relay, and webhooks, and adds self-hosting, an agent inbox, and monthly tiers with a self-host exit ramp. Stay on SendGrid if you are deeply embedded in subuser/IP-pool workflows with deliverability tooling your team already operates.

### How does Reloop pricing compare to SendGrid?

Reloop Pro is $10/month for 50,000 emails and Growth is $20/month for 100,000 emails, with overage at $0.50 per 1,000. SendGrid Essentials lists around $19.95/month for 50,000 emails and roughly $34.95/month at 100,000 emails — often with annual enterprise commits on top. Self-hosted Reloop has no Reloop license fee. Prices are public list prices as of September 17, 2026; verify on sendgrid.com/pricing and reloop.sh/pricing.

### Can Reloop handle SendGrid-scale volume?

Hosted Pro ($10/mo, 50,000 emails), Growth ($20/mo, 100,000 emails), and Enterprise target growing throughput; overage is $0.50 per 1,000. Self-hosted Reloop scales with your Kubernetes or bare-metal footprint.

### What about dedicated IPs?

Growth includes 1 dedicated IP and Enterprise is optional/custom. Self-hosted deployments can attach your own IPs directly to your MTA layer.

### How do templates and subusers migrate from SendGrid?

Inventory subusers, API keys, and IP pools and map each to Reloop orgs or environments. Export dynamic templates and contact segments, rebuild automations in Reloop campaigns or via API triggers, then run shadow traffic by duplicating transactional sends to Reloop in staging with real payloads before cutover.

### Does Reloop replace SendGrid marketing campaigns?

Yes. Reloop includes broadcast campaigns, templates, and contacts alongside transactional sends in one codebase — so marketing and engineering share a single template source of truth instead of a dashboard/API split.

### Is Reloop open source?

Yes. Reloop is Apache 2.0 licensed plus additional Reloop Labs terms: personal and internal self-host is allowed; commercial redistribution, third-party hosted services, and competing products are not. See https://reloop.sh/license.

### When should we stay on SendGrid?

Stay if your subuser hierarchy, IP pools, and deliverability tooling are already tuned, your annual commit pricing is favorable, and you have no need for source access, self-hosting, or agent-inbox workflows. Reloop wins on ownership, monthly flexibility, and unified transactional plus marketing sends.
