SMTP System Is Working But Contact Form 7 Cannot Send Mail

Hello,

I am using the WP Mail SMTP by WPForms plugin.

I send mail via SMTP and this plugin works smoothly.

I installed the Mailster – Email Newsletter Plugin for WordPress plugin, then sending mail via Contact Form 7 stopped working.

I disabled the plugin but still cannot send mail via Contact Form 7.

Test mail works via WP Mail SMTP by WPForms.

I can still send mail from other contact forms, but the form I created via Contact Form 7 gives error.

Could you help?

Thanks.
