How we grade them
| 2.4GPASendLayerFair | 2.2GPASMTP2GOFair | |
|---|---|---|
| Value for money | A$5 a month billed annually for 1,000 emails, under the $6 that is 60% of the category's cheaper quarter. The volume is small and the year is paid up front. | 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 | DA trial of up to 200 emails and no permanent free plan; the page does not say whether a card is needed. | 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. Enough for a test, tight for a live app. |
| Features | CSMTP and an API, email logs, open and click tracking, suppression and domain authentication, but the listing shows no inbound mail or IP pools and logs last 3 to 30 days. | 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 | CNo store rating on record. You verify a sending domain with DNS records and wire up SMTP credentials or an API key before the first email goes out. | 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 | BA web dashboard and an API; the listing names WordPress and WooCommerce. | 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 | transactional email for WordPress sites | relaying email from apps, sites and office printers |

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.
