What makes MailPace different
Why we are what you need
MailPace can only be used for Transactional Email - think password resets, notifications and welcome emails. We don't mix them up with slow, bulk marketing emails like other providers.
We're not just an API layer to another email service. We run our own SMTP servers, the way email was designed
We don't do helpdesks, NPS scores and clueless support scripts. Email us anytime and an engineer will get back within a few hours: support@mailpace.com
We're not owned by a billionaire, we're an independent company helping to get Transactional Emails to inboxes for our customers
Our API and interface is super simple & easy to use, and we have code libraries and integrations for most frameworks ready to go
We refuse to invade a person's privacy. Unlike other transactional email providers, we donβt support spy pixels or click tracking
We have a five-layer approach to ensuring that our service is never used for spam. Keeping your reputation high and getting your emails to inboxes
Our Transactional Emails arrive in seconds, and we continuously monitor and optimize our time to inbox scores to get emails to inboxes fast!
We use 100% carbon-neutral, renewable energy powered servers. Our servers are provided by local bare-metal & VPS providers, not massive cloud companies
Eco-Friendly, European-Focused, Privacy First.
Carbon Neutral Infrastructure
Our email infrastructure runs on 100% carbon-neutral, renewable energy powered servers
Local, European Providers

We put privacy first
No read tracking - we only check if the receiving server accepted the email, we never invade a person's inbox privacy.
Anti-Spam
No spam - we enforce DKIM validation, actively remove spammers and automatically check all outbound emails for spam.
