Import Subscribers

Quickly import your email subscribers from another platform.

This guide will show you how to import a CSV file of your subscribers so that they’ll be notified each time you publish a post on your site.

Add up to 100 subscribers

People with a free Jetpack plan may import up to 100 subscribers. This counts both towards a bulk .csv import or adding subscribers manually one at a time.

Add up to 10,000 subscribers

If you upgrade your plan to Growth, Social, Security, or Complete, or if you have our legacy Jetpack Creator plan, you can import up to 10,000 subscribers.

No matter what plan you have, there is no limit to number of people who can choose to subscribe to your blog directly via your subscription form.

Writing engaging content and promoting it via Jetpack Blaze or to your social media is a great way to have more followers.

Before you import

Get permission

Please ensure that you have permission to email your subscribers. If we receive complaints from your subscribers about spam, or if your emails have a high bounce rate, we may take action against your account.

Clean up your list

Subscriber list hygiene is important for successful imports. If our tools suspect that too many of your email addresses are invalid, your import may fail.

Do your best to have a clean and updated list when importing your subscribers to Jetpack. When you have an old list or if you haven’t sent any emails to your subscribers in more than 1 year, it is very likely that over 10% of the email addresses no longer exist because people change jobs.

To prevent this from happening, we strongly suggest that you clean your subscribers’ lists using a third-party service, such as the ones listed below:

Kickbox (free up to 100 addresses)
Emailable (free up to 250 addresses)
Proofy
EmailListVerify
NeverBounce
Klemail (France)
emailvalidation.io (free up to 100 addresses)

Import your subscriber list

To import subscribers, follow these steps:

Head to your Subscription dashboard at https://cloud.jetpack.com/subscribers/YOURSITEURL.
Click the Add Subscribers button at the top right end of the screen.
If you have just a few email addresses to add, you can type them in the boxes provided. Alternatively, click the uploading a CSV file link to select a file from your computer.
Click the Add subscribers button after you have made your selection.
You also have the option to import from Substack; if that’s so, select that option and follow the instructions by adding your Substack URL.

You can either manually type in email addresses, or upload a CSV file that you downloaded from another email platform. When uploading a CSV file, all email addresses in your CSV file will be imported.

You can import subscribers directly into specific Newsletter categories, both manually and via CSV uploads, via the Jetpack Cloud dashboard.

The feature is available on Jetpack Cloud → Subscribers when the Newsletter module, Newsletter categories, and categories are all enabled and selected in Jetpack → Settings → Newsletter. You can read more about that on the Newsletter Categories documentation page.

Manage your subscribers

You can view your imported subscribers from your dashboard by clicking on Users and then clicking on the Subscribers tab.

Here, you can:

Click Add Subscribers to add more subscribers.
Remove individual subscribers.

Publish a Post

When you publish a post, an email is sent to all your email subscribers. When you click Publish on a new post, scroll down until you see the number of subscribers to which the post will be sent.

Jetpack will only send out notifications for new public posts. Publishing other content types (like pages or a custom post type) or updating an already published post will not send a notification email.

Migrate subscribers from a WordPress.com site

If you want to migrate subscribers from a WordPress.com website to a self-hosted Jetpack-connected site, you can use our Subscription migration tool. This method is only available for sites hosted on WordPress.com that do not have plugins enabled.

If your WordPress.com site has plugins enabled, or you’re unsure about your site’s configuration, please contact support.

Troubleshoot issues with subscribers import

Errors during import

If you face any errors importing a CSV file of followers, here are a few things to verify first:

Go through your subscriber email list and make sure that all of the email addresses are valid. If we detect any invalid email addresses, the import will not work.
Make sure you have collected all your subscriber email addresses by yourself and that you have not purchased any subscriber lists. We take spam very seriously, and your email list will be blocked if we detect known spam addresses.
If you have lots of email addresses, try importing them in smaller batches of 500 each (this only applies if you have Growth, Social, Security, Complete, or the legacy Jetpack Creator plan).

Here is a list of common subscriber import errors, and what you can do about them:

Error Message	Explanation	Suggested Action
Can’t start subscriber import while another one is running.	Another import is already running.	Make sure you haven’t started imports in another tab. Otherwise, contact support.
No subscribers have been submitted.	An empty file was submitted.	Examine your CSV file and double-check whether it’s empty.
The CSV file does not contain information.	The CSV file is empty.	Examine your CSV file and double-check whether it’s empty.
You cannot add more subscribers on the free plan.	It is only possible to import up to 100 subscribers without a paid Jetpack Creator, Jetpack Social plan or bundled Jetpack plan.

You are not allowed to manage subscribers for the specified site.	The user account does not have permission to manage users on the site (likely because the account has a different role).	Try performing the action from an administrator account.
Your recent import is taking longer than expected to complete.	–	Contact support.
Any other error	–	Contact support.

Subscribers not imported

If you receive an email saying that not all of your subscribers have been imported, here’s why:

Some email domains are known spammers or abusers, so we block such domains from receiving email.
The email address you tried to add is associated with a WordPress.com user account that has chosen not to receive email.
The email address has too many pending invites for subscriptions.
