Hey there @cfm168
The MailChimp for WooCommerce plugin can handle a high volume of customers. There is no limitation set on the number of customers that can be synced with the plugin.
I went ahead and did some testing and did not find any conflicts or unexpected behavior while running Contact Form 7 on the site. However, I would recommend testing in your own server environment to be sure things work smoothly with your setup.
Finally, I’d just like to clarify that our plugin only syncs customers who made a purchase in WooCommerce. This plugin does not pull information from other plugins such as Contact Form 7. I might recommend looking for a separate integration or plugin that will connect Contact Form 7 directly to MailChimp.
If you have any further questions about the MailChimp for WooCommerce plugin, feel free to let us know.
