SMTP Servers are the ones that are created for ease of yours. SMTP bulk mail server allows you to send emails to a large number of contacts or groups. Daily Sender is the only bulk email marketing service that offers unlimited contacts for every account. Other Bulk Email Services restrict you based on subscribers where we don’t. You can have as many contacts in your lists as you want, there is no limit. We only limit you on how many emails you can send on daily bases.
