Gmail's "Send as" feature allows users to send mail from other email addresses or aliases they own within the Gmail interface. When sending mail in Gmail, users can choose a different "From" address; these addresses can be other non-Gmail addresses such as Yahoo or Outlook, a work, school, or business domain or alias, or another Gmail address. Users can set up to 99 different sender addresses.
Important change: Starting in January 2027, Gmail will no longer support the "Send as" feature for third-party email addresses (such as @yahoo.com or @outlook.com). This change does not affect Google Workspace aliases or other Gmail addresses owned by the user.
Usage consists of three steps:
- Add an address: On a computer, open Gmail and click "Settings" > "See all settings" in the top right, then click the "Accounts and Import" or "Accounts" tab. In the "Send mail as" section, click "Add another email address," then enter the name and the address you want to send from. Click "Next" > "Send verification." For a school or work account, enter the SMTP server (for example, smtp.gmail.com or smtp.yourschool.edu) and the username and password for that account. Click "Add account."
- Confirm the address: Sign in to the added account, open the confirmation email from Gmail, and click the link.
- Change the "From" address: When composing a message, click the "From" line (if you do not see it, click the blank space next to the recipient email) and select the sender address to use.
Users should check the Spam or Bulk Mail folder for the message from send-as-noreply@google.com. If trying to add a work or school account, ask the administrator to configure a domain alias and an email alias. If recipients use Outlook or another mail service, they may see something like "From yourname@gmail.com on behalf of othername@otherdomain.com." In the following situations, recipients may also see the original @gmail.com address: a vacation responder is set, a filter with an automatic reply is created, or the mailbox is full and the recipient receives a notification.
If you do not want to send from a certainAlias sending email or alias invalid, you can delete the email or alias. If you send email from an invalid alias, you will receive a bounce message. Deletion steps: Click Settings > See all settings, click the "Accounts and Import" tab or the "Accounts" tab, in the "Send mail as" section, click "Delete" next to the email address you want to delete. If you receive a bounce message from a valid email address and need to re-verify, you must first delete the address in "Send mail as", then add it again.
If you want to always send email from another address, you need to change both the default "From" and "Reply-to" addresses. If you only change the "From" address, replies will be sent to the original Gmail address by default. To always send email from another address or alias: In the "Send mail as" section, click "Make default" to the right of the address you want to use. When you send email, replies will be sent to the original Gmail address by default. To choose another address, follow these steps: Click the "Accounts and Import" or "Accounts" tab, in the "Send mail as" section, click "Edit info" next to the email address, click "Specify a different reply-to address", add the reply-to address, click "Next Step" if necessary, click "Save Changes".
If you see the "Cannot access server", "TLS negotiation failed" error, you may need to choose a different port number and authentication type. Make sure you are using the correct outgoing mail server for the provider. You may need to contact the third-party email provider to get the correct settings. Check the port number, authentication type, or outgoing mail server recommended by the other mail service. Make sure the third-party provider supports SSL or TLS with a valid certificate. Common combinations: SSL port 465; TLS port 25 or 587. It is recommended to send email over a secure (encrypted) connection. However, if the other mail service does not support these secure connections or does not use a valid certificate, you can choose port 25, then choose the "Unsecured connection" option that appears. If you do this, the information will not be encrypted.
Using Gmail aliases: A simple way to categorize email is to add a category after your username. For example, email sent to the following aliases will all go to janedoe@gmail.com: janedoe+school@gmail.com, janedoe+notes@gmail.com, janedoe+important.emails@gmail.com. Step 1: Choose aliases. Think about how to categorize your email, then choose an alias for each category. For example: use yourname+work@gmail.com for work email, use yourname+news@gmail.com to sign up for newsletters, use yourname+shopping@gmail.com to create online retailer accounts. Step 2: Filter email. Create filters to perform automatic actions, such as: adding labels or stars, forwarding to another account, archiving, or deleting. If you use Gmail with a work or school account, you can send email from a group alias. To receive verification email sent from a group alias, you need to grant a delegate access to that group. You need group permissions to change other members' access permissions. Open Google Groups, click "My groups", under the group name you want to send from click "Manage", on the left click "Permissions" > "Posting permissions", in the "Posting" section click the down arrow, select "Anyone on the web".
Limitations: Starting January 2027, the "Send as" feature for third-party email addresses will no longer be supported. This change does not affect Google Workspace aliases or other Gmail addresses owned by the user. Recipients may see "on behalf of" or the original Gmail address. Differences in third-party mail services' support for secure connections and certificates may cause configuration issues.
