Which one is for you
Pick Acumbamail if
- Fits if you send few emails to a big list and want to pay by sends, not subscribers
- Makes sense if you want email, SMS and landing pages in one account
Look elsewhere if
- Tight if you stay free: 250 subscribers and 2,000 emails a month
- Pricey if you need list cleaning, automatic resend or Facebook audiences, which start at $100 on Pro
- Skip it if you need a dedicated IP, which only comes with Enterprise at $316
- Watch out: the page shows euros first, and its annual dollar prices display in euros
- Not for you if you want a phone or desktop app, as it is web only
Pick Mailrelay if
- 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
Look elsewhere if
- 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

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.
