Every client on a different platform. Every platform with its own login, its own invoice, its own export button. MailerPress brings every campaign back into WordPress — the editor you already know, one licence for all your client sites, and contacts that never leave your server.

Segment on what people actually bought. Test two subject lines and let the winner send itself. See the revenue a campaign brought in, right next to the open rate. MailerPress does all of it inside WordPress — where your content, your products and your customers already live.

Your store already sends eleven emails you never designed — order confirmations, invoices, refunds, password resets. And it doesn’t send the ones that pay: the abandoned cart, the thank-you after a first order, the renewal reminder before a subscription lapses. MailerPress fixes both, and reports the revenue each one brought in.

Your list grows, your invoice doesn’t. Unlimited contacts on every licence — because a nonprofit shouldn’t pay more each time a supporter signs up. And the data stays on your own server: donors, volunteers and members, with the proof of consent stored next to every address.
