When system emails arrive from a generic Kickcall address, Businesses are more likely to mark them as spam or distrust them. SMTP setup lets you send every system email — notifications, OTP login codes, verifications and other transactional messages — from your own domain instead.

SMTP Setup Overview

SMTP Setup allows Agency administrators to connect their email provider to Kickcall so platform-generated emails are sent using the Agency's branded domain instead of the default Kickcall sender. You can configure SMTP credentials, set the sender name and email address, and verify that system emails are delivered correctly. Proper configuration helps maintain brand consistency, improve email deliverability, and ensure important communications, including login OTPs, reach recipients successfully.

Important notes

Most providers require SPF, DKIM and sometimes DMARC records on your domain so emails are not marked as spam. Complete your provider's domain verification before going live.
Incorrect credentials will stop all system emails, including login OTPs, from sending.

Before you start

An account with an SMTP-capable email provider (for example Mailgun, AWS SES, ZeptoMail, SendGrid, Postmark or Brevo).
An SMTP user or API key created in that provider, and your sending domain verified with them.
Your SMTP username, password, host address, domain, port, From email and From name.

Configure SMTP

Open Configuration → SMTP.

Enter the SMTP Username and SMTP Password from your email provider.

Enter the SMTP Address (host), SMTP Domain and SMTP Port.

Enter the SMTP From Email and SMTP From Name recipients will see.

Select Configure to save.

Trigger a system email, such as a login OTP or a test user invitation.
Check the inbox for the email and confirm it arrives from your configured From email and From name.
Confirm the email is not flagged as spam.
