Hi Amit,
This sounds like email marketing? I used to work for an email service provider
and here is what I would recommend:
Don't underestimate the whole deliverability aspect - this can be a lot of
work. E.g. Depending on the types of messages being sent and the providers
whose customers will receive these messages, you should take care of the
following:
Ensure you use SPF, Domainkeys and DKIM
Make sure that hardbounces with reasons like "user unknown" (which SHOULD be
5.5.0, but is not always) get unsubscribed from whatever mailing is in
question. Some providers (e.g. AT&T/bellsouth) will degrade your throughput if
you reach a threshold of too many wrong (usually obsolete - peaople change
providers more often than you'd expect) addresses.
Make sure that unsubscribes are honored.
In general, conform to can-spam, etc. if you don't, I have seen things happen
like the network provider being forced to shutdown the IP in question, etc.
Given the volume, it might also make sense to look at the providers
feedback-loop type programs. E.g. you absolutely HAVE to stop sending to people
who used the 'this is spam' button in web based services such as AOL, etc.
If you don't, you can quickly experience a full block of your outgoing IP by
that provider.
Check out the large providers' postmaster service pages to find out information
on what they require you to do to ensure good deliverability. This might be
anything from throttling to using SPF/Domainkeys, etc. Compare that with the
majority of addresses in the address pool that is going to be sent those emails
so you know where to focus on.
Last but not least: For mass mailings, some providers (e.g. AOL) will wait to
determine the traffic patterns coming from an IP address that was not yet used
for mass mailings: IF they determine that the pattern suggests normal usage
(regular newsletters, transactional messages, etc.) the deliverability will
pick up, but at first it WILL BE BAD. This is NORMAL. :-)
Thanks,
Martin
