We help you get your work done anywhere.
MailChimp works on desktop browsers, tablets, and mobile devices. So whether you’re at the office, at home, or somewhere in between, you can always work on campaigns and check in with your team.
We have features for serious marketers.
A/B split testing
People who A/B test their email campaigns get 11% better open rates and 17% more clicks.
Use autoresponders to create and schedule automated messages to welcome new subscribers, follow up on purchases, send birthday coupons, and more.
Track trends and monitor list growth, see the impact your campaigns have on social networks, measure you ROI, and more. We have reports for everything.
We'll make your team more productive.
We know that for many organizations, email marketing is more than a one-person job. That's why MailChimp is optimized to make collaboration easy and efficient.
Share comments right inside the drag-and-drop editor, send test emails with notes about your drafts, and collect replies to drafts in line with the rest of your comments. Several people can even edit campaigns at one time.
Set up a MailChimp account as an Admin, and grant permission to Managers, Authors, and Viewers, based on the level of access you want them to have.
We’ll grow with you.
Even if you're just getting started, we have simple tools to help you build your list and engage your subscribers. As you get bigger and better, MailChimp will scale right along with you.
Target your readers
Segment your list by signup date, location, purchase activity, and more. We make it easy to get your message to the people who want to hear it most.

We know how to deliver email.
MailChimp has an advanced delivery infrastructure and a smart delivery team. We watch our rates like a hawk (and you should too).
MailChimp’s abuse-detection technology keeps our system clean by predicting bad behavior in a campaign before it even gets out the door. Omnivore is always at work in the background, analyzing emails, processing new data, and preventing abuse on a massive scale.
Our internal abuse desk monitors our system with Cloudmark and Barracuda, the same powerful filtering technology that major ISPs use to block spam.
Large corporations and financial institutions use authentication to prove their emails aren't forgeries, so they don't get blocked by overly suspicious filters. MailChimp supports DKIM, SenderID, SPF, and Domain Keys automatically and free.
IP Address Ranges
To protect our deliverability, Mailchimp uses hundreds of IP addresses located in multiple data centers. These IPs are grouped into different reputation levels based on list‑member activity. We monitor our IP acceptance rates with ReturnPath, a leading third‑party deliverability vendor, and depending on which group of IPs an email is sent from, inbox acceptance rates range from 96‑99 percent.
We don’t just analyze your bouncebacks to clean your list—our abuse monitoring system detects potential delivery issues by actively scanning bounce logs for cryptic messages from spam filters and email servers.
ISP Feedback Loops
We’re registered with all the major ISPs to receive alerts whenever your recipients report your campaigns as junk or spam. If that happens, we instantly unsubscribe those members from your list in order to keep you (and MailChimp) from being blocked in the future. We’re on feedback loops with AOL, Hotmail, Comcast, Yahoo, USA.net, Cox, Earthlink, and more.
Even though most ISPs are transitioning to feedback loops, some still employ whitelists. MailChimp is registered with them and actively works to maintain our whitelisted status.
We stay current on industry and technology standards as members in email and ISP organizations including the ESPC (Email Sender and Provider Coalition), AOTA (Authentication and Online Trust Alliance), MAAWG (Messaging Anti-Abuse Working Group), and EEC (Email Experience Council).
We invest in our own infrastructure.
Though we like to think MailChimp has a fun and creative vibe both in and outside of the office, we take engineering and infrastructure very seriously. MailChimp has hundreds of servers spread out around the world, and uses CDNs and Akamai Web Application Accelerator to ensure speed and stability. With multiple copies of our users' data ready at all times, we've got ample redundancy, the ability to do maintenance without downtime, and many layers of protection against data loss.
We send A LOT of email.
We started working on MailChimp in 2001, and we’ve built a rock-solid infrastructure that supports millions of customers. In a typical month, we deliver 7 billion emails—that’s 236TB of outbound data across our delivery servers. Our servers handle:
