SMTP Setup
Email notifications will be sent from our email server [email protected]. Use SMTP so your forms send emails reliably using your own email provider (instead of the default sending service).
Why Use SMTP?
Using SMTP allows you to send emails directly through your own email provider (Gmail, Outlook, Zoho, custom domain, etc.).
Better email deliverability
Allows emails to come from your domain
More control and fewer deliverability issues
If you set up SMTP, the email notification will be sent from your own email address. (optional)
The sender will be your SMTP email address, not [email protected].
What you need to do:
Set SMTP in the app settings
Apply the app settings to each form

❓ FAQs
1- Why can’t I send a test email?
If the test email fails, it means the SMTP configuration is not working yet. Usually one of the values is wrong.
Please double-check:
✅ Email username – is it your full email address?
✅ Password / App password – copied exactly, no spaces?
✅ SMTP server – correct host name from your provider?
✅ Port – matches the encryption type (e.g. 465 for SSL, 587 for TLS)?
✅ Encryption – set to the value your provider requires (SSL or TLS)?
If everything looks correct and it still doesn’t work, please contact us at [email protected].
2- Do I need an App Password for Gmail / Outlook / Yahoo?
Some providers do not allow normal passwords for SMTP.
You should generate an App Password if you use:
Gmail / Google Workspace
Outlook / Hotmail
Yahoo Mail
iCloud Mail
3- Can I use a free Gmail account for SMTP?
Yes, BUT:
You must enable 2-Step Verification
You must generate a Google App Password
4- What’s the difference between SSL and TLS?
Both encrypt your emails.
SSL (port 465) → more secure, recommended
TLS (port 587) → alternative if SSL is not supported
Use the option recommended by your email provider.
4- Is SMTP required?
No. SMTP is optional. If you don’t want to use it, the app will send emails using the PowerfulForm system email by default.
