@getnoticedlocally Hi,
I hope you are doing well.
Thank you for sharing your experience with us. It’s sad to hear that you had to face challenges after the update. We understand your concern, and our support and development team is on high alert; can you download this?Beta version, test it and let me know the result? Our team is working hard to make the current plugin more stable and secure per the latest standards. We are also improving our QA process for this product to avoid such issues as much as possible in the future.
We have planned some new features and improvements in the roadmap, giving you more control over this plugin. Your input and suggestions will add significant value during this transition.
Also, Let me know which mailing service you are using with Post SMTP.
Thanks and regards,
Support Team – WPExperts
