Does this plugin work without Mailster?

No. It is an addon for the Mailster Newsletter Plugin . The plugin header requires Mailster. There is no separate minimum Mailster version in this addon.

Do I need a Google Analytics account?

You need a Google Analytics property if you want the hits to show up in Google Analytics. In the plugin, paste a GA4 Measurement ID. There is no API key, OAuth connection, or Google account login inside WordPress. This plugin is not a Google product.

What is the difference between G-Tag ID and Web Property ID?

G-Tag ID is the GA4 Measurement ID ( G-XXXXXXXXXX ). It prints the current gtag.js snippet on the newsletter web version. Web Property ID is the legacy Universal Analytics ID ( UA-XXXXXXX-X ) and prints the older ga.js snippet. Use the GA4 ID for current reporting.

When are the UTM parameters added?

If the campaign has Mailster click tracking turned on, the email link stays a Mailster tracking link and the UTM parameters are added when Mailster redirects after the click. If click tracking is off, the parameters are placed on the link in the email HTML. Parameters already present on a link are kept and override the matching default.

Can each campaign have its own UTM values?

Yes. On Newsletter → Settings → Google Analytics , enable campaign-based values. The campaign editor then shows a Google Analytics box for source, medium, term, content, and name. Finished and active campaigns lock those fields, and so does an autoresponder while its statistics are open.

Are links to other websites tagged?

Only when External domains is enabled. On first activation that option is on, so links to other hosts get the same UTM parameters. Turn it off to tag only links on this site’s domain.

Is subscriber data sent to Google?

The plugin does not export your subscriber list. Two things can still reach Google or the destination site:

• If you save a Measurement ID or a legacy property ID, the newsletter web version loads Google’s script and sends a page view to that property.
• UTM values are part of the link URL. If you put %%SUBSCRIBER_EMAIL%% or %%SUBSCRIBER_HASH%% in a UTM field, that value is included in the URL. The default campaign name is the campaign title, not the subscriber’s email.

Does this replace Mailster’s click reports?

No. Mailster still records opens and clicks in Mailster. This addon adds Google Analytics campaign parameters, and optionally a tag on the newsletter web version. It does not send form-signup events.
