Speed Control's, Number of Messages Per Connection
If an ISP detects a high rate of email delivery attempts from a specific IP address, the ISP is likely to assume you're spam and begin to block incoming emails from that IP address. Speed controls allow you to set the number of SMTP transactions that XMS can send over a specific time period to a recipient ISP's MTA. This decreases the likelihood that the ISP will block your email.
Additional options that can be set include number of delivery attempts per hour, retry period, bounce period and authentication method. This further protects your reputation as a legitimate sender of bulk email and reduces the possibility of being flagged a spammer.
Critical email delivery features:
"Just thought I would drop you guys a quick note and say "Thank you!" for all
the work and effort put into our bulk mail infrastructure. I am happy to
say that we sent around 850,000 messages today between 9 - 5 without an
issue or a complaint from any of our clients! I am confident that even
as the holidays approach and this volume will increase that we will finally
be able to handle this without a hitch.
Thanks again and keep up the good work!"
