How to send Email from your Stackmail account using Gmail
In this guide, we'll walk you through the process of sending emails from your Stackmail mailbox using Gmail as an SMTP (Simple Mail Transfer Protocol) client.
This enables you to harness the power and convenience of Gmail, while keeping 20i email as your primary platform.
You will need:
- SMTP Hostname – this is smtp.stackmail.com
- Mailbox name – the full email address you wish to send from (i.e. info@example.com)
- Mailbox password – if you do not know this, you can reset your password using these steps.
Log in to your Gmail account
- Open your web browser and go to Gmail (https://mail.google.com/).
- Log in with your Gmail account credentials. If you don't have a Gmail account, you can create one for free.
- Once logged in, click on the gear/cog icon (⚙) in the upper-right corner of the Gmail interface.
- From the drop-down menu, select See all settings.
Configure Gmail as an SMTP client
- In the Gmail settings page, click on the Accounts and Import tab.
- Scroll down to the Send mail as section and click the Add another email address link.
- A popup window will appear. Enter your name and the email address associated with your 20i mailbox.
- Click the Next button.
Configure SMTP settings
- In the next window, you will need to enter smtp.stackmail.com as the SMTP Server.
- Select port 587.
- For the username and password, enter your full 20i email address and the associated password.
- Ensure the Secured connection using SSL option is selected.
- Click the Add Account button.
Verify ownership
- Gmail may send a verification code to your 20i email address. You will need to retrieve this from the Stackmail mailbox, using either webmail or your existing email client setup.
- Enter the code in the verification window to confirm ownership.
Send Emails via Gmail using Stackmail SMTP
You've now successfully configured Gmail to send emails through your 20i SMTP server with the hostname "smtp.stackmail.com."
When composing a new email in Gmail, you can now choose to send it using your 20i email alias by clicking the "From" field and selecting your 20i email address.
By following these steps, you've seamlessly integrated your 20i email services with Gmail as an SMTP client. This enables you to enjoy Gmail's user-friendly interface while using your 20i mailbox as the backend, making email management more efficient and convenient.
