Which SMTP server should I use to send email?

Sending Emails using SMTP

Many of our hosting accounts are provided with your own shared SMTP server based on your domain name however many ISPs are now blocking 3rd party SMTP use in an effort to control SPAM on their networks.

If you use a third-party SMTP server server based on your domain name it may be classed as a spam risk. Sometimes, only emails sent through a dedicated ISP SMTP server have the best chance of delivery.

Use your ISP SMTP Server for best performance

When to use mail.yourdomain.co.uk

Most of our tutorials show your email configuration using the SMTP server mail.yourdomain.co.uk, however, you should use your ISP SMTP server in its place for the best and most consistent results.

If your ISP does not provide you with an SMTP service, then try using mail.yourdomain.co.uk as your SMTP server, this will work for most email networks.
