One reliable server for every email your systems send

Mailpro SMTP Relay lets you integrate any system or application to send transactional emails — order confirmations, receipts, password resets, alerts — plus your bulk campaigns. Point your app to our server and make sure every message reaches the inbox.

Deliverability at scale

Send high volumes without getting blocked

ISPs and hosting providers throttle large sends and burn your IP reputation. Mailpro's robust infrastructure and optimised routing handle big volumes with excellent delivery rates, while a team of experts keeps the sending IPs clean so you stay out of spam.

QUESTIONS

Frequently asked questions

What is an SMTP relay server?
An SMTP relay server sends email on behalf of your app, CRM, CMS or website. Mailpro's SMTP relay routes your transactional and bulk email through reputation-managed IPs so it reaches the inbox instead of the spam folder.
How do I connect to Mailpro's SMTP server?
Point your application or software to our SMTP server using the credentials in your Mailpro account (Settings → SMTP). No code required — it takes only a few minutes.
Does it improve deliverability?
Yes. Reputation-managed IPs, SPF and DKIM authentication and a robust infrastructure built for high volumes keep your messages out of spam.
Where is my data stored?
Mailpro's servers are located in Switzerland, so your data is protected by strict Swiss privacy laws and GDPR compliance.
Can I track transactional emails sent via SMTP?
Yes. A dedicated SMTP statistics section tracks opens, clicks, geolocation and bounces for every transactional message — separate from your campaign statistics.
