Connect Facebook Lead Ads and MailerLite

Facebook lead forms bring in the names; MailerLite sends the welcome series that turns them into customers. FlowMattic adds each lead as a MailerLite subscriber and drops them in the group whose automation should start, chosen by form or by answer. Older leads can be pulled in too. Built for small businesses and agencies running lead ads.

When Facebook Lead Ads fires New Lead, FlowMattic runs Create or Update Subscriber in MailerLite with the data from that event.

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

Facebook Lead Ads and MailerLite 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

Subscribe each new Facebook lead in MailerLite

The lead's email and name go straight into MailerLite with Create or Update Subscriber, so the welcome email reaches them while they still remember the ad.

New LeadCreate or Update Subscriber

Put each lead form's leads in its own group

A Lookup Table maps every lead form to a MailerLite group, so the ebook form starts the ebook automation and the webinar form starts the webinar one.

New LeadCreate or Update SubscriberLookup TableAdd Subscriber to a Group

Subscribe only leads who ticked the marketing question

If your lead form asks for consent to emails, a Filter lets only the yes answers through, which keeps MailerLite free of people who never agreed to hear from you.

Send hot leads and nurture leads to different groups

A Router reads an answer such as timeline or budget. Ready-to-buy leads join a sales group with a short follow-up, the rest join a longer nurture sequence.

Import leads collected before the workflow was on

Run Retrieve Leads once for the form, loop over the results and subscribe each person, so the first weeks of a campaign are not left out of MailerLite.

Split full names into first and last name fields

Many lead forms ask for one full name. Text Formatter splits it, so MailerLite emails can greet people by first name instead of their whole name.

Set up: new leads as MailerLite subscribers

At the end, each lead from the form you choose is added to MailerLite as a subscriber.

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

Create or Update Subscriber matches on email, so a person who fills in two forms is updated rather than added twice.
Joining a group is what starts most MailerLite automations. Add the subscriber to the group the automation listens to, not only to the account.
The lead fields depend on your form's questions, so the mapping above is an example. Create custom fields in MailerLite before mapping to them.

Why run this pair with FlowMattic

Facebook Lead Ads and MailerLite connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.

Lead details pass your own server

Names, emails and phone numbers go from Facebook to MailerLite through your WordPress site, not through another automation provider.

Campaign spikes cost nothing more

Runs are unlimited, so a lead ad that brings in thousands of leads in a week runs on the same plan.

Pick the group per lead

Lookup Tables and Routers place each lead in the group whose automation fits the form or the answers they gave.

Common questions

How do I connect Facebook Lead Ads to MailerLite?

Add both accounts under Connects, start a workflow with the Facebook Lead Ads New Lead trigger and add MailerLite Create or Update Subscriber. Map the email and name, test with a test lead and switch the workflow on.

Will the MailerLite welcome automation start for these leads?

Yes, if the automation starts when a subscriber joins a group. Add the lead to that group with Add Subscriber to a Group after creating the subscriber.

Can MailerLite tell me which ad a lead came from?

Map the form name or ad details from the lead data into a MailerLite custom field, then segment or report on that field in MailerLite.

Can I send leads from several Pages into one MailerLite account?

Yes. Build one workflow per Page or form, all pointing at the same MailerLite connection, with a different group or source field for each.

Do MailerLite triggers do anything here?

They can start separate workflows, for example when a lead unsubscribes or completes an automation, but Facebook Lead Ads can only retrieve leads, so they cannot change anything in Facebook.
