F.A.Q
An SMTP server (Simple Mail Transfer Protocol) is a service that allows you to send emails over the Internet. At SMTP Builder, we build high-performance, customizable SMTP servers to ensure reliable email delivery for marketing, transactional, or bulk messaging.
There is no sending limit. This is an unlimited SMTP server as it is built on your own VPS, meaning you can send as many emails as needed — perfect for bulk email marketing or high-volume communication.
You can use any email application that supports STARTTLS (TLS 1.2) authentication. That includes Outlook, Thunderbird, Sendy, MailWizz, Mautic, and many more. Our SMTP servers integrate easily with all up-to-date third-party apps.
Yes, you can receive emails too. We support both IMAP and POP3, so you can access incoming messages using any standard email client or service.
Since your SMTP server is hosted on your VPS, it will remain fully operational as long as your VPS hosting and domain subscriptions are active. If you cancel either service, your SMTP server will no longer be accessible.
Your SMTP server can be blacklisted if spam rules are violated. Our tool reduces this risk by using a subdomain to protect your main domain. To avoid blacklisting, send only to opted-in contacts, keep lists clean, and monitor your server’s reputation.
