You can keep Gmail as the place where mail arrives while customers see your business address, such as brian@yourcompany.com, when you reply. You do not need to move your Gmail messages or change the way you read them.
The easiest way to understand the setup is to separate three jobs:
| Job | Example | What it does |
|---|---|---|
| Inbox | yourname@gmail.com |
Holds the messages you read in TrekMail. |
| From address | brian@yourcompany.com |
The address your customer sees. |
| Sending service | TrekMail or your saved SMTP service | Delivers the outgoing message. |
SMTP is simply the service that delivers outgoing email. You do not need to understand the technical details to use this feature.
A real-world example
Brian publishes brian@thegroovyroamer.com, but mail sent there is forwarded to thegroovyroamer@gmail.com.
After the setup:
- A customer writes to
brian@thegroovyroamer.com. - The message arrives in Brian's Gmail inbox.
- Brian reads it in TrekMail and clicks Reply.
- TrekMail automatically chooses
brian@thegroovyroamer.comin From. - The reply is delivered through the sending service Brian selected.
- The customer sees the business address, not the Gmail address.
- A copy of the reply is kept in the connected Gmail account's Sent folder.
Brian can still choose another available address from the From menu before sending.
Before you start
You need all three of these:
- A Gmail, Outlook, or other inbox connected to TrekMail.
- An active business domain in the same TrekMail account.
- The business address assigned to your mailbox with Sending turned on in the Dashboard.
TrekMail will not offer a made-up or unapproved address. This protects your domain and stops someone from sending as an address they do not own.
Forwarding is separate from this setup. If your business mail should arrive in Gmail, arrange that forwarding with the service currently receiving the business mail. Adding a From address does not create forwarding by itself.
Set it up
1. Connect the inbox
- Open TrekMail webmail.
- Open Settings → Connected accounts.
- Click Connect an account.
- Add Gmail, Outlook, or another inbox and finish the connection test.
For Gmail, follow Add Your Gmail Account to TrekMail.
2. Make the business address available
An account administrator does this in the Dashboard:
- Open Mailboxes and choose your mailbox.
- Add the business address as an alias, or open the existing address.
- Make sure the address is active and Allow sending from this address is on.
Return to webmail after the change. The address will now be available for sending.
3. Link the address to the connected inbox
- Open Settings → Sending addresses.
- Click Add a From address.
- Choose the connected inbox where the mail arrives.
- Choose the business address customers should see.
- Confirm the sending method.
- Add a sender name, Reply-To address, or signature if you want them.
- Click Add From address.
The screen shows the finished path in plain language:
- Mail arrives in — the connected inbox.
- Recipients see — the business From address.
- Sent using — the service that delivers the reply.
Choose how the address sends
Most people should keep Use the domain's sending settings. TrekMail then follows whatever is already set for that business domain:
- Managed TrekMail SMTP on an eligible plan, or
- the custom SMTP profile selected for that domain in the Dashboard.
Choose Use a different saved sending service only when this one From address needs a different provider. For example, the rest of yourcompany.com might use TrekMail while sales@yourcompany.com uses a saved Mailjet profile.
The connected Gmail account is still the inbox. Choosing a different sending service does not move incoming mail and does not change the Gmail password.
Make replies choose the right address
At the top of Settings → Sending addresses, choose one of these:
- Address that received the message — best when several business addresses feed the same inbox. Replies try to use the address the customer wrote to.
- Default address for new messages — replies start from your normal TrekMail default instead.
For the Gmail-forwarding example, choose Address that received the message.
TrekMail checks the original delivery details and the visible To and Cc addresses. If the message matches a business address linked to that connected inbox, the reply uses it automatically. You can always check or change From before sending.
Useful ways to use it
Keep an existing Gmail workflow
Continue receiving mail in Gmail, but stop exposing an @gmail.com address to customers. This is useful for a freelancer or small business that is not ready to move its inbox.
Run several brands from one webmail
Connect more than one inbox and add an approved From address for each brand. New messages let you choose the brand from the From menu, while replies can choose it automatically.
Move gradually instead of all at once
Keep an old provider running while a domain is being moved. TrekMail can read the existing inbox and send from the approved business address during the transition.
Use different delivery services
One address can follow its domain settings while another uses a saved SMTP profile. This is useful when a client, brand, or campaign must use its own delivery provider.
Offer the same workflow under your own brand
White Label customers use the same Connected accounts and Sending addresses screens on their branded dashboard and webmail domain. The provider's name, logo, colours, and links are shown instead of TrekMail branding, while each customer's connected inboxes, domains, and SMTP profiles remain separate.
Personal inboxes and team inboxes are different
A Gmail account connected to your personal mailbox stays personal. Teammates do not get access to it simply because they share another TrekMail mailbox with you.
For a team address such as support@yourcompany.com, use a TrekMail shared mailbox. Members with Can reply permission can read and send from that shared address. Do not connect one person's Gmail account and expect it to become a shared team inbox.
What this feature does not do
- It does not share your Gmail password with teammates.
- It does not let you send from an address that is not approved in your TrekMail account.
- It does not create mail forwarding automatically.
- It does not move old Gmail messages into a TrekMail mailbox.
- It does not make a personal connected inbox visible inside a shared mailbox.
- It does not change your domain's DNS or sending service unless an administrator changes those settings.
If something does not work
The business address is missing: Ask the account administrator to confirm that the address belongs to your mailbox, is active, and has Allow sending from this address turned on.
The sending method says it is not ready: Open the domain's SMTP tab in the Dashboard. Finish either Managed TrekMail SMTP or a custom SMTP setup, then return to webmail.
A reply chooses the Gmail address: Confirm that the business address is linked to that exact connected Gmail account and that Address that received the message is selected. You can choose the business address manually from From while checking the setup.
Sending fails: Test the selected sending service in the Dashboard. If you use a saved custom SMTP profile, check that its password is still valid and that your provider allows the business From address.
The sent copy is missing in Gmail: Reconnect the Gmail account and check that its Sent folder is available. Sending and saving the Sent copy are separate steps.
