Some businesses run on more than one WordPress: the membership on one site, the list and everything else on another. An email written on either one still needs the facts from both, so ResultsAiX Email can go on both sites and link them. Activating the licence on both uses two of your three slots.
Where to find it:
Open AiX Email and click the Family data tab. The first card, This site runs more than one WordPress, holds the role and the token. The second card, Linked sites, holds the list and the Add a site form.
Core and satellite:

What this site is offers two roles. The choice saves as soon as you change it.
- Core, the library lives here: where emails are written and kept. It gathers facts and level names from every linked site.
- Satellite, it just contributes its data: it answers the core's requests. Its Mailer picker can still browse the core's library when its own is empty.
Which one should be core: the site the Mailer is on. Writing an email and loading it into a broadcast is the daily job, and it wants to be one screen, not two sites. Membership facts are small and slow moving and travel fine over a link.
This site's link token:
The token is what the other site uses to read from this one. It is shown masked, with Show and Copy buttons. It is read only: facts, level names and the library. Never subscriber rows, never keys.
Make a new one replaces the token after asking Make a new token? The old one stops working the moment you do, so any site using it has to be given the new one.
Linking two sites:

- On the other site open AiX Email, Family data and set What this site is to Satellite.
- Under This site's link token press Show, then Copy.
- On the core site open Family data and go to Add a site.
- Fill in Call it, for example Members site, Its address, for example https://members.yoursite.com, and Its token.
- Press Link it. The link is tested straight away and a message says what it found, for example Linked to the site's name, its role, how many emails it holds and which sources it can see. The page then reloads.
If the test cannot reach the other site, the message gives the reason in plain words. Check the address and the token, and that the plugin is active on the other site.
What travels:
Facts, level names and the library listing. Never subscriber rows, never keys. It is read only in both directions and nothing is ever written to the other site.
What you will notice:
- Level names from the other site appear in the Membership level lists.
- In the facts block, anything from the other site is labelled with the site it came from, so two sites' numbers are never blended into one sentence. Facts from linked sites are refreshed hourly.
- Overview lists your linked sites under What it can see, marked linked or off.
- Diagnostics tests each linked site and shows its name and email count, or why it could not be reached.
Managing a link:
Each linked site shows its name, an on or off pill and its address, with a Test button and a remove button. Test shows the site's name, role and sources in a short message. The remove button asks Unlink this site? Nothing on either site changes. They just stop talking.
A worked example:
Sam runs the Bread Club on members.yoursite.com and the Mailer on yoursite.com. Sam installs the plugin on both, sets the members site to Satellite and copies its token. On yoursite.com, Sam adds Members site with the address and token and presses Link it. From then on the level picker on yoursite.com lists Bread Club Monthly and Bread Club Annual, and renewal emails can quote how many annual memberships run out this month.
Tips:
- Make the site the Mailer is on the core.
- If you ever think a token has been shared too widely, press Make a new one and give the new token to your other site.
