Use this type for email hosted with a provider other than Microsoft 365 or Gmail — for example, your company’s domain hosting.
If your email is Microsoft 365, use Microsoft 365 Connect. If it is Gmail, use Gmail App Password.
📋 What you need
The sending (SMTP) details of your mailbox, which your provider gives in their customer area or documentation:
- Sending Server (for example,
mail.yourdomain.com) - Port and whether it uses SSL
- Username and password of the mailbox
If you want GC to read the replies to the emails it sends (Read and answer replies option), you also need the incoming (IMAP) server and its port, which the provider lists in the same place.
⚙️ Setup in GC
Go to Administration >> Email >> Sending Accounts, click Add and choose the Basic Authentication type.
| Field | What to fill in |
|---|---|
| Server | The provider’s sending (SMTP) server |
| Port | Usually 587 or 465 |
| SSL | Checked on port 465; unchecked on port 587 (the connection is still protected, as long as the server allows it) |
| Username | Usually the full email address |
| Password | The mailbox password |
| E-Mail: From / Name | Sender and name the recipient sees |
| IMAP Server | Only with Read and answer replies: the provider’s incoming (IMAP) server, for example imap.yourdomain.com or mail.yourdomain.com |
| IMAP Port | Only with Read and answer replies: usually 993 |
Save and click Test.
❓ If the test fails
- Confirm server, port and SSL with your provider (these are the most common errors).
- If you changed the mailbox password, update it in GC as well.
- If sending works and only reading fails, check the IMAP server and port; the username and password are the same as for sending.
- Some providers limit the number of emails per hour: for large mailings, check that limit.
