Troubleshooting

If you cannot send emails please make sure that your email client has been setup properly. If you haven't already, please follow the setup instructions for your email software.

In particular, check the following:

1. Your Email Address:
   Check that the email address you are sending from (the one in the 'From' field) matches either your 'billing' email address or one of your 'additional' email addresses in your account. You can change your email addresses by logging in.
2. Outgoing Server:
   Check that the Outgoing Server (or SMTP Server) in your email software is set to smtp2go.com.
   Be sure to double-check that you have not misspelt the server as 'smpt2go.com' or 'stmp2go.com'. If you are unsure where to find this, please see the setup instructions.
3. Port Number:

This is a critical check! SMTP2Go works on ports 25, 2525, 8025 and 587. To determine if a particular port is blocked from your location, please do the following in Windows.
(Note: Windows 7/Vista users may need to install Telnet to perform the test below, as these operating systems do not come with Telnet pre-installed. To add Telnet in Windows 7/Vista, go to Control Panel -> Programs -> Turn Windows Features On or Off and check Telnet Client).

1. Click the Start button, and then click "Run..." (Windows 7 users press WindowsKey + R)
2. Enter "cmd" and press Enter
   
3. In the window that appears, enter "telnet smtp2go.com 2525". If port 2525 is available you should see "220 smtp2go.com ESMTP Exim..." appear after a few seconds. If this does not appear, then close the window and repeat the steps above, using ports 25, 8025 and 587. For example, to test port 8025 enter "telnet smtp2go.com 8025".

In almost all cases using port 2525 will work, however some ISPs may block port 2525. In these cases using the port number that you have determined is able to work above will alleviate the problem. Important- some PDAs may not have a separate field in which to enter a port number. In this case it is recommended that you enter the Outgoing Server of smtp2go.com:2525 (the port number must follow the server name, separated by a colon).

If none of the above ports is working for you then please try using the following setup:
     SMTP server: port80.smtp2go.com
     Port: 80

Problems sending large attachments are normally caused by a slow upload speed at your current location. You can check your current potential upload speed here: speedtest.net (then click 'Begin Test'). At slow locations, we recommend sending a zip file of your attachments, or using sendspace.com.

Some devices (fax machines etc.) may benefit from using the IP address of 207.58.142.213 instead of smtp2go.com as the SMTP server.

Finally, our controlled location setup often works in highly controlled locations (such as China).

If you are still having problems then please contact us using the form below and we will promptly respond.
