How to Easily Connect Your Web Applications with mySMTP
If you use web applications to send newsletters, invoices, or transactional emails, you will be happy to know that connecting them to mySMTP is quick and straightforward.
Whether you are running a webshop, a CRM, or a marketing automation tool, our SMTP relay makes sure your emails are delivered reliably — every time.
Why integrate your web applications with mySMTP
By sending your emails through mySMTP, you benefit from higher inbox placement, secure encrypted connections (TLS 1.2), and a centralized setup that works across all your systems. You can also easily monitor your sending activity and performance in one place.
How to get started
- Log in to your mySMTP account and find your SMTP host, username, password, and port.
- Use TLS 1.2 on port 587, or alternative ports 25 or 2525 if your system requires it.
- Enter these details in your web application’s SMTP settings.
You can integrate mySMTP with all major platforms — for example MailWizz, Instantly, Mumara, Interspire, Magento, WordPress and many more.
Once configured, send a test email and check your logs in the mySMTP dashboard to confirm everything’s running smoothly.
