Charitable and Mailster: Grow Your Donor List With Every Donation
The Charitable + Mailster integration adds a newsletter opt-in checkbox directly to your donation forms. When a donor gives, they can subscribe to your Mailster list in a single click – no separate signup form required.
Manual list-building is slow and error-prone. This integration removes that friction entirely. Your Mailster subscriber list grows automatically every time someone completes a donation.
The result is a healthier email list full of people who are already invested in your cause. Engage them with updates, impact stories, and future campaigns – all powered by Mailster.

Frequently Asked Questions
Do you have a question about connecting Mailster with Charitable? See the list below for our most frequently asked questions. If your question is not listed here, please contact us.
How does the Charitable + Mailster integration work?
The integration uses the Charitable Newsletter Connect extension to add an opt-in checkbox to your donation forms. When a donor completes a gift and checks the opt-in box (or if you use automatic mode), their information is sent directly to your chosen Mailster list. Because Mailster is a WordPress plugin like Charitable, no API connection or external account linking is needed. The two plugins communicate internally, which makes setup fast and the connection reliable.
Do I need an API key to connect Charitable to Mailster?
No. Mailster runs directly on your WordPress site, so the Charitable + Mailster connection does not require any API keys or external credentials.
Which donor information syncs to Mailster when someone donates?
When a donor opts in, their name and email address are added to your selected Mailster list. This gives you a clean, up-to-date subscriber record for every donor who agrees to receive your newsletter. The sync happens at the moment the donation is completed, so there’s no delay between giving and subscribing.
Can I choose which Mailster list donors join?
Yes. You can set a default list that applies across all your campaigns. You can also override this on a per-campaign basis, just open the campaign editor, click the Newsletter tab, and select a different list. This lets donors from different campaigns into different subscriber lists automatically, without any manual sorting afterward.
Can I customize the opt-in label that appears on my donation forms?
Yes. You can write a custom label for the newsletter opt-in checkbox.
