I recommend using Mail Mint.

I have been using the paid version of Mail Mint since spring 2023. I recommend using Mail Mint. If you send a question email to Mail Mint support, they will reply very quickly. Mail Mint is also excellent in basic performance. For example, if you use Mail Mint to register for a newsletter, after submitting your email address, an opt-in email will be sent to that email address. Then, by clicking the link in the email, you will complete your registration for the newsletter. In this way, the procedure of checking whether the email address is active impresses users that the website uses robust email software, and greatly increases credibility. As of October 2024, there are many systems in operation that do not send such opt-in emails when registering an email address. If there is no opt-in email, a third party can register someone else’s email address. Mail Mint has a system that impresses users that there will be no fraudulent registration of email addresses. You can also freely edit the text of the opt-in email. I use the WordPress Theme “Bricks Builder”, and the standard form of Bricks Builder and Mail Mint can be linked. When registering an email address for a newsletter, you can also set it so that users must check the privacy policy and terms of use. And by updating to the Mail Mint Pro version, you can remove the “Mail Mint” logo from emails sent to users. Here, we will compare email and SNS. There are rumors that one SNS, X, will introduce a small annual fee system worldwide. How many people may stop using X due to the small fee system worldwide? The percentage of SNS users is not as high as the percentage of email users. Therefore, when spreading information on a website, it is clear that it is correct to prioritize sending emails via newsletter registration over using SNS. Mail Mint has a recommended setting of “send up to 25 emails every 5 minutes” so that the display speed of the site does not slow down during email delivery. If you want to reliably deliver and manage newsletters from your website, Mail Mint is the recommended email delivery plugin. The emails you receive using Mail Mint are equivalent to those sent by large companies using expensive email delivery services. Mail Mint has excellent support, and if you have any problems, you can always consult with them and they will reply promptly. If you don’t mind having the “Mail Mint” logo on your emails, I recommend the free version of Mail Mint. I recommend Mail Mint.
