Which one is for you
Pick Inbound if
- Fits if your app needs to receive and answer incoming email
- Works for developers who want email handled by webhook
Look elsewhere if
- Skip it if you want to try it free, since no free plan or trial is listed
- Not for you if you send marketing or bulk email, which the page does not describe
- Tight if you run many domains, with 50 on the $15 plan and $3.50 for each extra
- Watch out: extra capacity is $16 per 50,000 received plus 50,000 sent a month
Pick Twilio SendGrid if
- Fits if you already use Twilio for texts or calls and want email from the same company
- Works for apps sending about 50,000 emails a month that want address checks, with 2,500 validations on Pro
Look elsewhere if
- Tight if you stay on Essentials, with 1 teammate and 3 days of email activity
- Skip it if you want a free plan that lasts, since the trial ends after 60 days
- Pricey if you need SSO, subusers or a dedicated IP, which start with Pro at $89.95 a month
- Watch out: sending past your plan's volume can add overage charges the pricing page doesn't list
- Not for you if you want newsletters on the same plan, as Marketing Campaigns is separate, from $15 a month
How we grade them
| 1.8GPAInboundWeak | 2.6GPATwilio SendGridGood | |
|---|---|---|
| Value for money | B$9 a month for 5,000 emails is at the edge of the cheaper quarter of email tools. Extra domains are $3.50 each and extra capacity $16 per 50,000. | 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 | FNo free plan and no trial are listed, so every email is paid for from the first 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 | CEmail to webhook, address routing, threaded replies, API and CLI, spam filtering and retries. It does that narrow job fully, and does not describe bulk sending. | 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 rating on record. It is an API and CLI product, so setup means DNS, webhooks and code. | 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 | CWeb dashboard, API and CLI only. No integrations list is shown. | 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 | receiving and replying to email by API | 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.
