How we grade them

|---|---|---|
| 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: Essential is $25 for exactly that, on a shared IP, which is the middle of this category at that volume. Reputation Defender and Insight Engine add $5 a month each, and a dedicated IP means Starter at $80 for 100,000. |
| 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. | FNothing free: no free plan and no trial. The smallest plan is $25 a month, so you pay before you've sent a single email. |
| 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. | CSMTP relay and an email API, detailed delivery reports, dedicated IPs from the $80 plan, and paid add-ons that weed out bad addresses as you send. It handles the sending, but nothing on record covers templates, webhooks or inbound email. |
| 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: you choose a plan and pay before you get to send, then use SMTP or the API. No rating on record.
