Connect WordPress and Mailbluster

MailBluster sends your newsletters and promotions, and WordPress holds the people who sign up, comment and buy memberships. FlowMattic adds them to MailBluster as leads at the moment it matters: when an account is registered, a comment is approved or a role changes. It is for site owners who want their email list built from real site activity.

1. TriggerNew User

2. ActionCreate a New Lead

When WordPress fires New User, FlowMattic runs Create a New Lead in Mailbluster with the data from that event.

You build this in the FlowMattic workflow builder on your own site. See the setup steps

WordPress and Mailbluster workflows you can build

Each one uses only triggers and actions the two integrations ship today, plus FlowMattic's own tools. Where the library has a ready-made template, import it instead of building from scratch.

Ready-made template

Add each new WordPress user as a MailBluster lead

Everyone who registers on the site joins your MailBluster list with their name and email, so welcome and product emails reach new accounts.

New UserCreate a New Lead

View the template

Add only users who get a customer or member role

Sites with many roles, such as authors or shop managers, keep staff off the marketing list by filtering on the role that was added.

User Role AddedFilterCreate a New Lead

Turn approved commenters into newsletter leads

Readers who join the discussion are often the most engaged. Once a moderator approves their comment, their email goes to MailBluster, ideally with a consent checkbox on the comment form.

Comment ApprovedFilterCreate a New Lead

Add members who upgrade from free to paid

When a role changes from subscriber to a paid member role, the person is added as a lead, ready for the emails you send paying members.

User Role Changed From Specific to DefinedCreate a New Lead

Add users who tick a newsletter box in their profile

A profile field such as newsletter_opt_in starts the workflow when it changes, and the Filter passes only users who switched it on.

User Profile Field UpdatedFilterCreate a New Lead

Bring existing users of a role into MailBluster

People who registered before the workflow existed are added too. Fetch every user with the role once, loop over them and create a lead for each.

ScheduleGet All Users by RoleIteratorCreate a New Lead

Set up: new users as MailBluster leads

At the end, every account registered on your site appears in MailBluster as a lead.

Add MailBluster with Create a New Lead and map the email, first name and last name, plus any tags you want on new users.
Test and switch on
Test the step, check the lead in MailBluster and switch the workflow on.

Triggers and actions in this pair

A trigger starts a workflow. An action is something FlowMattic does in the app as a step.

Good to know

These workflows use MailBluster's Create a New Lead, so data flows from WordPress to MailBluster only. Unsubscribes in MailBluster do not change WordPress.
There is no delete action for MailBluster, so when GDPR Erase Data Request Confirmed fires on your site, remove that lead in MailBluster by hand.
Many new users have no first or last name until they edit their profile. Map the display name as a fallback, or add the names later with a profile trigger.

Why run this pair with FlowMattic

WordPress and Mailbluster connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.

Your list grows from site activity

Registrations, approved comments and role changes become leads, so the list reflects who actually uses the site.

Pick exactly who joins

Filters on role, profile fields or comment consent keep staff, test accounts and people who did not opt in off the list.

No per-lead automation fees

FlowMattic runs on your WordPress site with unlimited runs, so a busy registration day costs nothing extra.

Common questions

How do I add WordPress users to MailBluster?

Create a workflow with the WordPress New User trigger and add MailBluster Create a New Lead, mapping the email and names. Every account registered after you switch it on becomes a lead.

Can I add users who registered before?

Yes. Run a workflow once with Get All Users by Role, loop over the result with Iterator and add Create a New Lead. Run it per role if you only want some users.

What happens if a lead already exists in MailBluster?

That depends on MailBluster, since Create a New Lead is the only action here and there is no lookup step. Test with an existing email before running a large import.

Can I keep administrators and editors off the list?

Yes. Start from User Role Added or User Role Changed instead of New User, or put a Filter on the role after New User, so only customer or member roles go through.
