If you’re able to receive emails but not send them, there are a few things that can be causing this issue. Before contacting us, try the following:
Check your email account’s configuration settings.
Make sure that your email settings match the settings from the following FAQ: How do I set up an email account?
Check if the person you are trying to email is in a position to receive your email.
Make sure that their email service is working, because if it isn’t, you won’t be able to send the email successfully until the problem is resolved on their end.
Consider your recent email activity.
Our email client has automated anti-spam filters to prevent people from using Cogeco to send unsolicited bulk emails. If you have been sending a lot of emails in a short time, or inadvertently use phrases similar to an active spam campaign, it's possible your email was temporarily suspended.
