I can receive email but can't send
Turn on "my outgoing server requires authentication" in your mail app's outgoing (SMTP) settings.
Cogeco Email: Settings, Sign-In & Fixes
Cogeco runs email for Ontario and Québec customers, and Québec addresses ending in cgocable.ca use their own server names. Sending fails until you turn on outgoing authentication.
Covers @cogeco.ca, @cgocable.ca. Run by Cogeco. Checked against Cogeco's own help pages, November 2026.
Cogeco email server settings
| Server | Address | Port | Security |
|---|---|---|---|

| Outgoing (SMTP) | smtp.cogeco.ca | 587 | STARTTLS; authentication required |
- Username: Your full email address. Québec addresses ending in cgocable.ca use imap.cgocable.ca and smtp.cgocable.ca instead.
- Use IMAP if you read mail on more than one device; POP downloads mail to one device only.

Common Cogeco email problems
I'm in Québec and the cogeco.ca servers don't work
cgocable.ca addresses use imap.cgocable.ca and smtp.cgocable.ca.
I forgot my Cogeco email password
Change it in My Account under Email management (or Services, Internet, Manage my email addresses).
My new password is still rejected
Sign in to My Account first to check the change went through, then update the password in each mail app.
I want to change my main email address
You cannot do this yourself; Cogeco has to change it for you.
Problems that look the same on every provider
Can't sign in, or the password stopped working
- Sign in on the provider's own webmail page first. If that works, the problem is your mail app, not the account.
- If webmail rejects the password, use the provider's "Forgot password" page. Never use a reset link from an email you did not ask for.
- Many providers now need a separate app password (or their own sign-in screen) for Outlook, Apple Mail and phone apps. Your normal password will not work there.
Not receiving emails
- Check Spam, Junk and any filters or "blocked senders" in webmail.
- Check whether the mailbox is full; most providers stop accepting mail at the storage limit.
- If your app shows nothing new but webmail does, remove and re-add the account in the app using IMAP.
Can't send, or emails are stuck in the Outbox
- Check the outgoing (SMTP) server, port and security on this page against your app; old guides often list ports that no longer work.
- Turn on "My outgoing server requires authentication" and use the same username and password as incoming.
- Large attachments are a common cause. Remove the attachment and try again.
Contacts are getting spam from my address
- Change the password from webmail, then sign out of all other sessions if the provider offers it.
- Check forwarding rules, filters and the reply-to address in settings; attackers often add a hidden forward.
- Turn on two-step verification, and update the password anywhere else you used the same one.
Setting it up on a new phone or computer
- Use IMAP rather than POP so mail stays in sync across your phone, computer and webmail.
- Enter your full email address as the username unless the provider says otherwise.
- If the app offers the provider by name (Yahoo, Google, Outlook), choose that instead of "Other".
