The report card
Best for transactional email for WordPress sites
SendLayer is a transactional email service over SMTP or API, aimed at WordPress sites, from $5 a month for 1,000 emails billed annually. There is no free plan, only a 200-email trial, every plan is billed yearly, and it is not for marketing campaigns.
| Subject | Grade | Comment |
|---|---|---|
| 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. |
| Free plan and trial | D | A trial of up to 200 emails and no permanent free plan; the page does not say whether a card is needed. |
| Features | C | SMTP 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. |
| Ease of use | C | No 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. |
| Platforms and integrations | B | A web dashboard and an API; the listing names WordPress and WooCommerce. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who SendLayer is for
- Fits if you run a WordPress or WooCommerce site and send order mail
- Works for small senders under 10,000 emails a month
Who it is not for
- Skip it if you want a free plan, as there is only a 200-email trial
- Tight if you want to pay monthly, since every plan is billed annually
- Watch out: your plan is upgraded automatically when you reach its monthly email limit
- Not for you if you send marketing campaigns, because it is a transactional service
- Tight if you need long logs, as Starter keeps 3 days
Good to know
Good for
- WordPress and WooCommerce sites that need reliable system emails
- Small senders who want a low entry price per month
- Sites sending a few thousand transactional emails a month
Worth knowing

- It has no permanent free plan, only a trial of up to 200 emails.
- Per its FAQ, a plan is upgraded automatically if you reach its monthly email limit.
- It is a transactional email service, not a tool for marketing campaigns.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace SendLayer you would be making mail servers with a good name among inbox providers. That is not a weekend's work, with an AI app builder or without one.
It costs $60 a year.
What you could not
- Mail servers with a good name among inbox providers.
- It plugs into other products, WordPress and WooCommerce among them, and has an API.
What this rests on. SendLayer’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
