Auto Email Sender uses SMTP server to send (like all mail clients, such as Outlook, etc., use SMTP to send mail). Using SMTP to send has its advantages and disadvantages.

Benefits of using SMTP to send emails

Using SMTP to send mail is a very common way, as long as your mail content is not spam, it will not be put into the spam mailbox.

Disadvantages of using SMTP to send emails

The SMTP server is generally provided by the mailbox provider. In order to prevent customers from sending spam, the mailbox provider will limit the number of emails sent by customers. In particular, the free mailbox limit will be stricter (some days, only a dozen or dozens of emails can be sent a day.), the paid mailbox limit will be relatively loose, but generally will also limit the number and frequency of emails sent every day.

Suitable users

1. The number of emails sent every day is small, from hundreds to thousands.
(Auto Email Sender has no limit on the number of emails, so this is based on your server limit. Again, DO NOT send spam!)

2. Website administrators or companies who send emails purposefully, the content of the email is not spam, and the email address is highly targeted, true and effective.

Inappropriate users

1. Sending emails to a huge number of customers, more than 10,000 email addresses. You need a larger online mail sending service instead of using SMTP sending tools.

2. Send unauthorized emails or spam.

Auto Email Sender is NOT a tool to generate spam!
