So what happens if you reach the maximum number of subscribers allowed in your lists?
Import Paused: Upgrade Action Required
A list import was started that will cause your total number of subscribers to exceed the 12,000 subscriber limit on your current account plan. We’ve paused the import so that you won’t exceed your plan limit. To resume the import, please upgrade your account.
Only an admin user can approve an account upgrade.
If you use a monthly subscription then you’ll likely encounter the above error message when trying to import or individually add new subscribers. The monthly plan may be upgraded or alternately, if you use multiple lists, then it’ll likely be beneficial to combine lists into a single list and use Groups.
The other thing to be aware of regarding importing subscribers is that those email addresses that will hard-bounce (i.e. undeliverable email addresses) will only be automatically removed from your list once you send your Campaign. If you want to save some money by removing email addresses that will hard bounce rather than import them into Mailchimp then why not use our list validation and verification service where we’ll remove the undeliverable email addresses (you also get three months free subscription from Mailchimp as we’re Mailchimp listed Experts).
You’ve hit your account subscriber limit. Your Forever Free plan can only send while your total subscriber count (all lists combined) is at or under 2000. upgrade to re-enable
Should you be using a free Mailchimp account then you’ll still be able to add subscribers to your list even if you hit the maximum number of subscribers allowed. You won’t however be able to send your Campaigns until you either remove the excess number of email addresses or upgrade your account.
