Email Campaign Delivery

We know how to deliver email

Mailchimp has an advanced delivery infrastructure and a smart delivery team. We’ll get your email where it needs to go so you can focus on running your business.

Mailchimp sends 6 billion emails a week.

And we make sure they get into your subscribers’ inboxes.

We’ll handle the technical stuff, you’ll get more opens and clicks

Mailchimp makes it easy for you to send your email without worrying about any of the technical details. Sure, we offer built-in domain authentication, bounce management, reports from Internet Service Provider feedback loops and whitelists, and hundreds of IP addresses across multiple data centers, but all you need to remember is that we’ll help more of your email reach inboxes, which means you’ll see higher open rates and more click-throughs.

24/7 abuse monitoring to protect your account

Our abuse-detection technology keeps our system clean by gathering information from billions of emails and predicting bad behavior in campaigns before they even get out the door. This technology is always at work in the background, analyzing emails, processing new data, and preventing abuse on a massive scale.

Email authentication built in

Authentication helps email servers and ISPs filter out spam from legitimate email campaigns. It makes your emails look trustworthy, which helps get them reach inboxes. That's why we automatically add 3 types of authentication to every email you send for free: DKIM, SenderID, and SPF.
