Your website can send email,
without touching a mail server.
We set up SMTP for contact forms, invoices, notifications, and system email. MXroute can be the backend while XessOne handles DNS, credentials, testing, and support.

What happens behind the scenes
Clients only need to know website email sends successfully. XessOne handles sender identity, DNS, credentials, and testing.
Sender identity
Choose sender addresses like hello@domain.com or no-reply@domain.com based on website needs.
DNS authentication
SPF, DKIM, DMARC, and return-path are prepared so messages have a clear identity.
App integration
We help install SMTP credentials into WordPress, Laravel, Next.js, or custom applications.
Delivery test
Send test emails to Gmail/Outlook, inspect headers, and confirm forms/notifications arrive.

Checklist before SMTP is considered ready
SMTP is not just host, port, username, and password. Healthy email needs consistent domain authentication.
Start with one contact form first.
Send the domain and the website/app stack. We recommend the lightest SMTP setup that still protects domain reputation.
