Rewritten Question (Clear Version)

You are asking:

Can Advanced Custom Fields (ACF) in WordPress be used to build an email broadcasting and subscription system where guests are connected to specific properties, and when they check in or claim a reservation, their email becomes associated with that property so they can receive targeted communications?

In other words:

Each property is a post (for example, a StayWithJay listing such as those under P2007, P2014, etc.)  A guest checks in using a reservation code. When they complete check-in, their email should be stored. That email should be tied to: That specific property Possibly a status (checked-in, past guest, VIP, etc.) Later, you want to: Broadcast emails to guests of a specific property Broadcast to all past guests Control subscription logic

And your question is:

Can ACF alone handle this kind of broadcasting/subscription logic?

Short Answer

No — ACF alone cannot run a full broadcasting or subscription system.

ACF is a data storage tool, not an email marketing engine.

However:

ACF can absolutely be used as the structured data layer behind a broadcasting system — if combined with:

WordPress users WPForms (which you are already using)  An email engine (WP Mail SMTP, FluentCRM, MailerLite, etc.) Custom logic or automation

What ACF Actually Does

ACF allows you to:

Add structured custom fields to: Posts (like properties) Users Custom Post Types (reservations) Options pages

ACF stores metadata in the WordPress database.

It does not:

Send emails Handle subscriptions Manage opt-in logic Handle unsubscribe links Run broadcast campaigns

The Correct Architecture (Professional Setup)

Here is how your system should be structured.

1. Data Structure Layer (ACF)

ACF should define structured relationships like:

On the User:

related_property (Post Object → Property) guest_status (Select: Checked-In / Past Guest / VIP) last_stay_date subscription_status (Subscribed / Unsubscribed)

On the Property Post:

Relationship field → linked guests Broadcast category (Construction, Healthcare, etc.)

This matches how your properties are structured in your listings table 

ACF = clean database architecture.

2. Data Collection Layer (WPForms)

You already use WPForms heavily 

When a guest checks in:

WPForms collects: Email Reservation Code Property On submission: Create or update a WordPress User Assign property via ACF field Set subscription flag

WPForms supports:

User Registration Addon Conditional logic Webhooks Email triggers

This is where your automation begins.

3. Email Engine Layer (Required)

To broadcast emails, you need:

Option A – CRM inside WordPress

FluentCRM Groundhogg MailPoet

These allow:

Tag-based segmentation Property-based campaigns Automated sequences Unsubscribe compliance

Option B – External Email Platform

MailerLite ActiveCampaign ConvertKit

Then sync:

ACF fields → tags Property → segmentation group

Why ACF Alone Cannot Do This

ACF stores data like this:

user_id

meta_key

meta_value

501

related_property

P2007

501

guest_status

checked_in

But it has:

No campaign scheduler No mass email sender No unsubscribe management No compliance tools No analytics

Broadcasting requires:

Email queueing Rate control Spam compliance Opt-out management

ACF does not provide these.

Best System for StayWithJay Specifically

Given your current infrastructure:

Properties structured (P2007, P2014, etc.)  Multiple WPForms check-in flows  CRM-like operational mindset

The correct architecture is:

ACF → Data Structure

WPForms → Data Capture

FluentCRM (or similar) → Broadcasting

This allows you to:

Email only P2007 past guests Email only VIP guests Email only healthcare stays Send property-specific announcements Send emergency notices per property

Compliance Consideration (Very Important)

If guests are required to verify identity before check-in, you must disclose this in your listing descriptions 

Similarly:

If you collect email for marketing or broadcasts, you must:

Clearly state consent Provide unsubscribe mechanism Follow CAN-SPAM rules

Your verification disclosure framework already demonstrates proper compliance thinking 

Final Conclusion

ACF is:

✔ Excellent for structuring property-guest relationships

✔ Excellent for tagging users

✔ Excellent for subscription metadata

ACF is NOT:

✖ An email broadcasting system

✖ A marketing automation engine

It must be combined with:

WPForms (which you already use)  A CRM/email engine
