IMPLEMENTATION:
————–
Main Server:
We will use the Main Server to:
– Install Interspire Email Marketing (With Multiple MTA)
– Install the Database
– Connect to cluster servers to send the mail
– Install NameServer
We can’t use the Main Server to send emails directly because if the main IP
is blacklisted all the Outgoing mails is blacklisted (arrive in SPAM)
Cluster / MTA Server:
We will use the Cluster Server to:
– Outgoing the mails
– Relay closed only for Main Server
– Configure SPF/SKIM/DomainKeys
– SMTP Server Optimization
– SMTP Server Cache implementation
– SMTP Smart Engine to manipulate the outgoing mails
– SMTP Smart Engine to manipulate the Bounced Mails
– Rotate the outgoing IP based in Domain (sender-from:) ie:
domain1.com: assigned 192.168.1.1
domain2.com: assigned 192.168.1.2
domain3.com: assigned 192.168.1.3
domain4.com: assigned 192.168.1.4
domain5.com: assigned 192.168.1.5
Mails with send-from:
domain1.com we will use the IP 192.168.1.1
domain2.com we will use the IP 192.168.1.2
etc.
etc.
================================================================
| Notice: The major ISP’s have limited the rate hour/day/recipients
| of mails:
| – Hotmail: 3500 – 5000 per day – per IP
| – Yahoo: 350 – 500 per day – per IP
| – Gmail/Aol/Others: 30.000 per day – per IP
|
|
| Then to send 1.000.000 (1 million) in 1 day we need:
| – Hotmail/yahoo: more than 128 IP’s
| – Gmail/Aol/Others: 28 to 32 IPs
|
| This method is used to not get blacklisted our IP’s
================================================================
Interspire Email Marketing:
Interspire with Multiple MTA:
—————————–
The principal problem with bulk mailing is get the IP blacklisted,
and the Interspire Limitation is “can’t use more than one SMTP server at same time”
With interspire we will do:
MTA: Mail Transfer Agent (SMTP)
First stage:
———–
– Install Multiple MTA addon
– Link the Contact List to one(or more) SMTP
– Optimize Databe<->Interspire cache
– Use Multiple MTA on the Fly (you can send one campaign with different MTA in the same time)
Second stage:
————
– Rotate SMTP in one contact list
– Rotate SMTP based in IP reputation
– Smart Engine to select SMTP based in the domain-to recipient
– Smart Engine to analyze the are recipient and use one SMTP on this area.
– Personalized bounce processing(maybe use a external Bounce Process API)
