A small UK email service

Your email, sent. Even when your provider says no.

ASMTP is a reliable UK service that gives your mail program, phone, printer or website a reliable way to send email when your internet provider blocks it, your address has been blacklisted, or your web host's outgoing mail keeps failing.

Real support, in the UK

Support replies fast, usually within a few hours. Prices are in pounds with nothing added.

Careful about who we let in

Every customer is checked and approved by hand before they can send. That keeps our sending addresses clean, which is what keeps your email landing in inboxes.

Who this is for

You work from home and your broadband provider blocks port 25 or bounces your mail.
Your office scanner or printer needs to email documents and the old settings stopped working.
Your website needs to send order confirmations or contact-form messages and they keep landing in junk or vanishing.
Your web host's outgoing mail is slow or unreliable and you cannot wait for them to fix it.
Your mail server's address has ended up on a blocklist and you need to keep sending while you sort it out.

What it is not

ASMTP is not for newsletters, marketing campaigns or bulk mail. If that is what you need, a marketing platform will serve you far better, and our limits will get in your way.
