Hi
thanks for the report.
It appears that sendy has changed their API somewhat and now requires an api key to be entered in the settings . I’ll update the WPPizza mailing list plugin to that effect in the next few days to make sure it behaves again.

Thanks

Should now be fixed (v1.4)
might take a few hours for an update to be shown as being available though in your wp backend
(depends on your exact wordpress setup and configuration)
Once it’s updated , get your api key from your sendy installation and enter it in the plugin settings (wppizza-> order settings-> mailinglists -> Sendy : Sendy ApiKey)

If you still have issues after that, let me know

Cheers

We aim to please 🙂

>Also, I noticed that the “location” and “Number” columns are not being transferred to Sendy via API.

there’s nothing like that provided by the api from what I can see
https://sendy.co/api#subscribe
so I do not really understand that comment to be honest

there’s a filter integrated you can use to alter/amend the past data as you require for your particular setup

$postdata = apply_filters('WPPIZZA_MLL_SENDY_parameters', $postdata, $customer_data, $order_details, $list_options );
