How we grade them
| 1.8GPAMailer To GoWeak | 2.6GPATwilio SendGridGood | |
|---|---|---|
| Value for money | CStarter is $15 a month for 25,000 emails, the middle of this category's prices. Extra email is $1.00 per 1,000, and a dedicated IP is $30 a month. | BGraded on 50,000 emails a month: Essentials is $19.95 for exactly that, in the lowest-priced quarter of this category at that volume. It comes with 1 teammate and 3 days of activity, and Pro at $89.95 is where dedicated IPs and SSO start. |
| Free plan and trial | FNothing free: there is no free plan or trial, so every plan is paid from day one. | 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. |
| Features | CSMTP sending, delegated DNS, suppression handling, delivery webhooks and inbound routing. The REST API is still in development, so sending today is SMTP only. | BAPI and SMTP, event webhooks, an inbound parse webhook, dynamic templates, domain authentication, address validation and EU data residency. That covers the job. Testing credits, subusers and dedicated IPs wait for Pro. |
| Ease of use | CNo store rating on record. It takes sending domains and DNS to set up, but it is a plain SMTP service. | 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. |
| Platforms and integrations | BWeb, SMTP, and Heroku, Addons.io and Build.io add-ons, plus Rails, Django, Laravel and Nodemailer guides. No apps. | 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. |
| Best for | SMTP sending for developers on Heroku or anywhere | app email for teams already on Twilio |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
