The report card
Best for a big free email plan with a logo
Mailrelay sends 80,000 emails a month to up to 20,000 people on a free plan, with an editor, automations and SMTP. Paid plans start at €48 for 100,000 emails and rise with volume, and transactional email and WhatsApp are paid trials. Free emails carry a Mailrelay logo.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | B | The free plan is large, but paid starts at €48 a month for 100,000 emails and climbs to €132 at 500,000, which is above the $20 category middle. |
| Free plan and trial | A | Free forever: 80,000 emails a month to up to 20,000 recipients. The cost is a Mailrelay logo in the footer of every email. |
| Features | B | Editor with AI, email and SMS automations, segments, landing pages, forms, SMTP and API, and statistics. The listed extras are paid on top. |
| Ease of use | C | No store rating on record. It is a web app where you build the lists, templates and automations yourself. |
| Platforms and integrations | B | Web app with an SMTP relay and API, plus Make.com and WooCommerce. No phone or desktop app is listed. |
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 Mailrelay is for
- Fits if you have a list under 20,000 and want to send for nothing
- Works for shops that need an SMTP relay and an API alongside newsletters
Who it is not for
- Pricey if you grow, as Standard goes from €48 at 100,000 emails to €260 at 1,000,000
- Tight if you want a clean footer, because removing the logo is a €4.95 a month add-on
- Watch out: transactional email is a 30-day trial then €14.95 a month, and WhatsApp a 10-day trial then €9.95
- Watch out: prices are in euros and priority queue, chat and phone support are on paid plans only
Good to know
Good for
- Small senders who want a sizable free plan
- Teams that also want SMS and WhatsApp from the same vendor
- Spanish-speaking senders: support is offered in Spanish
Worth knowing
- Prices are in euros and rise with monthly email volume: €76 at 250,000 emails on Standard, €260 at 1,000,000.
- Transactional email on the free account is a 30-day trial, then €14.95 a month; WhatsApp is a 10-day trial, then €9.95 a month.
- Free accounts carry a Mailrelay logo in emails; removing it is a €4.95 a month add-on.
- A prepaid option sells email credits instead of a subscription; annual billing takes 10% off.

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 Mailrelay you would be making newsletters sent to thousands of people that still reach the inbox. That is not a weekend's work, with an AI app builder or without one.
It is one of the better ones too: its GPA of 3.0 is higher than 99 of the 102 other email marketing and newsletter tools we grade. It costs $643.51 a year.
What you could not
- Newsletters sent to thousands of people that still reach the inbox.
- Email sent in volume that still reaches the inbox.
- Texts to thousands of numbers, registered with the carriers.
- Mail servers with a good name among inbox providers.
- Splitting visitors between versions and telling you which won.
- It plugs into other products, Make.com and WooCommerce among them, and has an API.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. Mailrelay’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.
