Whether you want to send ten or millions of emails, HTML or text, with or without attachments, our Postman manages this for you. You can also define a time scale or limit the sending of the emails. Of course you want that all your customers receive the message and no email will be removed by a spam filter falsely. This is also not a problem for this software.
