I can’t log in.

A number of things can interfere with your ability to log in to your MailChimp account. There may be a problem with your login credentials or account status, for example, or you may need to check your browser settings and network connection.

In this article, you’ll learn about what kinds of issues can prevent you from logging in to MailChimp, and how to address them.

MailChimp Login Credentials

For security purposes, MailChimp allows only 10 attempts to log in to your account before we'll lock your account for 24 hours. If you have trouble logging in to your MailChimp account with your username or password, here are some things you can try.

  • Request a username or password reset.
    If you forgot your username or password, use the I Forgot Username? or Forgot Password? links on the login page. The Recover Username option will send your username to the contact email address on file for your login, while the Reset Password option will send an email that will let you to reset your password. If you do not have access to the email address associated with your account, contact support.

  • Check your formatting.
    Usernames and passwords are case-sensitive, and spacing matters. Be sure to use the correct capitalization, and that there are no extra spaces before or after the text.

  • Log in through G Suite.
    If you set up your MailChimp account through G Suite, you'll need to log in via G Suite or set up a username and password before logging in through MailChimp.

Authenticator App Login Credentials

Two-factor Authentication is a system that adds an extra layer of security to protect your MailChimp data. When you enable an authenticator app in your MailChimp account, a unique passcode from the app on your mobile device is required each time you log in.

I received an invalid passcode error

Open the authenticator app on your mobile device to auto-generate a new passcode each time you log in to MailChimp. If your passcode is rejected, there are a couple troubleshooting steps that you can take.

  • Make sure the auto-generated passcode is for your MailChimp account.
    Your authenticator application could be connected to more than one service or account. Make sure the generated passcode is for the MailChimp account you want to access.

  • Use a valid authenticator passcode.
    Authenticator passcodes are valid for 30 seconds after they’re generated, as indicated by the timer icon. If a passcode is older than 30 seconds, relaunch the authenticator app on your mobile device, and enter the new passcode in MailChimp.

I lost my mobile device

If you lose your mobile device, use the backup code that was provided when you set up two-factor authentication in your account.

After you use your backup code, we'll generate a new one for you. Be sure to save the new backup code in a secure place and on a different device than the one you use for the authenticator app. If you lose your backup codes, you can generate a new set of codes on your settings page.

Account Status

To log in, your account must be active. If you think there may be an issue with your account status, here are some steps you can take.

  • Activate your account.
    When you signed up for MailChimp, we sent an email with an activation link that we use to verify your email address. If you haven’t clicked that link, your username and password aren’t active. Check your email for the account activation email, and click the link to activate your account, and then log in.

  • Verify that your account is still open.
    If it’s been a more than a year since you last logged in to MailChimp, or if you haven’t updated your credit card information, your account may have been closed or deactivated. To learn more, read My account was deactivated.

Browser and System Settings

Because MailChimp is a web-based application, browser and system settings may prevent you from logging in to your account. How to change these settings will vary from browser to browser. Try these help sites for more information: Google Chrome, Mozilla Firefox, Microsoft Internet Explorer, Safari, Microsoft Windows Edge.

If you suspect there may be issues with your browser or system settings, here are some possible solutions.

  • Log in through a different browser or private browsing window.
    If you're able to log in successfully in a different browser or private browsing window, clear your cache and cookies in the original browser and try to log in again.

  • Use the most recent version of a compatible browser.
    We can't promise full support for beta or developer versions of your preferred browser. To learn more, read our Minimum System Requirements.

  • Make sure JavaScript is enabled.
    MailChimp uses JavaScript for many features in the application, so make sure JavaScript is enabled in your browser. Each browser manages JavaScript settings differently. Search your browser’s help site to find out how to enable JavaScript.

  • Make sure cookies are enabled.
    MailChimp uses session cookies to help our website remember changes you make as you move from page to page. Each browser manages cookies settings differently. Search your browser’s help site to find out how to enable and clear cookies.

  • Remove browser add-ons or plugins.
    Add-ons and plugins can block cookies from being stored in your browser and may prevent you from successfully logging in. Search your browser’s help site to find out how to remove add-ons and plugins.

  • Check your clock and time zone settings.
    If you get a system clock error message, check and adjust your system clock and time zone on your computer, or set it to automatically synchronize using NTP.

Connection Issues

We work hard to make sure you always have a smooth, fast connection to MailChimp. If you experience connectivity issues, here are some things to try.

  • Run a network speed test.
    If you suspect your connection may be the problem, run a network speed test. If your connection speed number is lower than 1,000 kbps, your experience with the application may be slow or spotty. Ask your IT department or internet service provider if anything can be done to optimize your connection speed.

  • Find a WiFi connection that’s less restricted.
    If you log in to MailChimp from a free WiFi spot, such as a coffee shop, the connection to our site may be blocked. These places often have restrictions on the types of websites you can use, or have unwritten time limits that may end your session abruptly. Some even turn off their WiFi coverage during lunch-rush hours. If you’re working from a location with highly restrictive WiFi, you may need to change locations or use a VPN.

  • Lower your maximum transmission unit (MTU) settings.
    If you’re connected via Digital Subscriber Line (DSL), an incorrect MTU setting allows many sites to work without any issues, but can cause problems when you connect to more complex sites, like MailChimp. Try to lower your MTU settings, or contact your internet service provider about how to do so.
