The Arial Software Technical Department
recently put Campaign
Infinity to the test. Our lab techs wanted to find
out just how fast the permission email marketing software
could send assorted emails. These test HTML emails
ranged from messages with no merge fields to messages
with five merge fields and set for database writeback.
The results of these tests are posted here.

Conclusion
The more personalization
features within the message, the more sending time is
needed. Emails with the least number of merge fields
moved fastest, while those with more merge fields moved
with less speed, in direct relation to the number of
merge fields used in the message. Those email messages
with more merge fields and set to write back to the
database moved with the least speed.
This testing involved two different
computing platforms using the same operating systems,
the same Ethernet connections, the same mail server
simulator and the same two databases, each of those
loaded with one million records. See Arial's Email
Marketing Bandwidth Requirements Chart to determine
the bandwidth you'll need to achieve the highest speed
possible.
