How we grade them
| 2.6GPATwilio SendGridGood | 2.2GPASMTP2GOFair | |
|---|---|---|
| Value for money | BGraded on 50,000 emails a month: Essentials is $19.95 for exactly that, in the cheaper quarter of this category at that volume. It's thin for the money, with 1 teammate and 3 days of activity, and Pro at $89.95 is where dedicated IPs and SSO start. | CGraded on 50,000 emails a month: Starter is $30 a month at that volume, with two months free if you pay yearly. That sits in the middle of what this category charges for that much sending. A dedicated IP and email testing need Professional at $75. |
| Free plan and trial | CNo lasting free plan, but a 60-day trial with no card: 100 emails a day, enough to wire it into your app and test. After that you're paying. | CFree for good with no card: 1,000 emails a month, but only 200 a day, with 5 days of reports, and extra emails can't be bought. Chat and phone help last 14 days. Fine for a test, tight for a live app. |
| Features | BAPI and SMTP, event webhooks, an inbound parse webhook, dynamic templates, domain authentication, address validation and EU data residency. That covers the whole job. Testing credits, subusers and dedicated IPs wait for Pro. | CAPI and SMTP sending, automatic SPF and DKIM, delivery reports with bounce alerts, blacklist monitoring, three data regions and subaccounts. It does the sending job fully, but that's a smaller job: nothing on record covers receiving email or templates. |
| Ease of use | CJudged on how fast a developer sends a first email: client libraries, interactive API docs and a setup guide on every plan, but you'll authenticate a domain before mail goes out properly. No rating on record. | CJudged on how fast a developer sends a first email: copy the SMTP details or use the API, with code examples in five languages, once your domain is added. No rating on record. Sign-up refuses Gmail and Yahoo addresses, so you need a work domain. |
| Platforms and integrations | BWeb, with a REST API, client libraries, SMTP and webhooks, so anything that speaks SMTP can use it. The listing names no ready-made integrations, and there's no desktop or phone app, so B is the top. | BWeb, with an SMTP relay and REST API that work from apps, servers and devices, plus WordPress, Google Workspace, Salesforce, Zoho CRM, Pipedrive, WHMCS, Laravel and Django. No desktop or phone app, so B is the top. |
| Best for | app email for teams already on Twilio | relaying email from apps, sites and office printers |
