The Email screen with SMTP host, port, credentials and test controls

Email — your own SMTP, with a required test before it goes live.

Your customers receive email from your panel — invitations, password resets and account notices. Those emails carry your brand whether or not you configure anything here.

​
What happens with no setup

Emails to your customers are automatically rebranded: your business name replaces GFXToolz, and links point to your domain rather than ours.
A customer who gets a password-reset email from your panel is sent to your sign-in page, never to a GFXToolz one. This works out of the box.
The one thing you cannot change without SMTP is the sending address — the technical from header.

​
Sending from your own domain

​
required
Your provider’s SMTP server, e.g. smtp.yourprovider.com.
​
required
Usually 587 with STARTTLS, or 465 for implicit TLS.
​
toggle
On for 465. Off for 587, where the connection is upgraded after connecting.
​
required
Usually the full mailbox address.
​
required
Your SMTP or app password. Write-only — once saved it is never shown again, not even to you. Leave it blank when editing other fields to keep the stored one.
​
required
The address customers see, e.g. support@yourbrand.com. It should be on a domain you control and match the account you authenticate with.
​
optional
The display name beside the address — usually your business name.

​
Test before it goes live

There is a send test email action, and it is not optional in practice: SMTP will not be used for real customer mail until a test has passed.
1

Save your settings

2

Send a test to an address you can check

3

Confirm it arrives — check the spam folder too

4

Enable it

Enabling untested SMTP is the fastest way to silently stop every customer email. If invitations and password resets stop arriving, check here first.

​
Landing in the inbox

Correct credentials get mail sent. Correct DNS gets it delivered.
Authorises your provider to send for your domain. Your mail host gives you the record.
Signs your mail so receivers can verify it was not tampered with.
Tells receivers what to do when SPF or DKIM fail. Start with a monitoring policy.
Use a real mail provider — Google Workspace, Zoho, Brevo, Mailgun, Postmark. Sending from a self-hosted server on a fresh IP usually means the spam folder.

​
Choosing a from address

Good

support@yourbrand.comhello@yourbrand.com

Avoid

noreply@ — customers do reply, and you want to receive it.A free Gmail or Yahoo address — fails authentication and looks unprofessional.

​
If you would rather not bother

Skipping SMTP is perfectly reasonable. Emails still go out, still carry your branding and still link to your domain — only the technical sending address is ours. Many resellers never configure SMTP, because they deliver temporary passwords over WhatsApp and barely use email at all. See Users.
