AdLelo Bulk Mail keeps your contacts and email templates in one place and sends to hundreds of people at once, from your own email address.
Import from CSV or paste emails, then group contacts into your own categories.
Write a mail once, save it, and pick it again whenever you need it.
Watch progress as mails go out and see which ones were delivered or failed.
Every account has its own lists, templates and reports. Nobody else can see them.
