Mailrelay, from Spain, is known for one of the most generous free plans in email marketing: 80,000 emails a month for up to 20,000 contacts. It also sells SMS credits and WhatsApp. The catches show up once you move to a paid plan — and that is where Mailpro™ makes a difference.

Here is a fair comparison of statistics, commitment, support, hosting and features.

See every open and click, on every plan

Mailrelay's Standard plan, at €48 a month for 100,000 emails, does not include open and click tracking. Without those numbers you cannot tell which subject line or offer worked.

In Mailpro, opens, clicks, bounces and unsubscribes are reported for every campaign whatever your plan, and you can segment contacts by their behaviour. Plans and credits are on the pricing page.

No 12-month lock-in

Mailrelay's monthly plans run on a 12-month commitment, and its prepaid packs expire after 12 months. With Mailpro you can buy credits when you need them or choose a monthly plan billed monthly or yearly.

Transactional email through the Mailpro SMTP relay and API is part of the platform, not a separate subscription.

A real person when something goes wrong

On Mailrelay, free users get ticket support, chat starts on Standard and phone support only on Enterprise. Mailpro answers by email and phone whatever your plan, under a published service level agreement.

Before each send, the anti-spam test flags content that could land in the junk folder.
