Travel SMTP solves your email problems

Travel SMTP accepts email from ANY network and ANY location. No matter what email software you use, or if you use a desktop computer, a notebook, tablet or smartphone, your outgoing mail will never get stuck again!

100% success guaranteed!

ISP's only accept email from their own network users

Internet Service Providers usually only accept traffic to their smtp server from their own network IP addresses, that means, only if you are on their network, you can use their smtp server. They do this in order to stop unsolicited spammers from using their smtp server to send spam.

Internet providers block tcp port 25

Another problem can be when you are using a SMTP server other than your ISP's SMTP server, your emails are being blocked by your ISP, simply because traffic on port 25 is being blocked, except for traffic to their own SMTP server. This is yet another way of trying to stop spammers, because very often people's computers are infected with viruses that will use their computer for sending spam directly to email servers. When this port is blocked, these viruses will no longer work.

Why Travel SMTP works where other SMTP servers fail

Travel SMTP accepts all connections

Travel SMTP will always accept your outgoing email, from any location, any network, any country, any device and any email software.

Firewall-Proof setup

Travel SMTP has a very unique Firewall-proof feature: in addition to listening on default smtp ports, it also listens on port 80 and 443. These ports are normally used for standard internet traffic, like regular traffic to websites. When you use this setup, no firewall will stop you from sending email: if you can visit websites, you can send email! This is extremely useful in hotels, campsites, WiFi hotspots and in some areas like China, or any other network where only regular internet traffic is allowed to pass through.

No webmail needed

You no longer need webmail when you are away from home. You use your own email program and your own email address(es). Unlike other SMTP servers, Travel SMTP does not show "on behalf of" in the "From" field.

Travel SMTP is fast and reliable. For only $23.50 per year you are freed from any more email troubles. Check our pricing plans or try Travel SMTP for free:
