How To Select Number OF Dedicated IP(s) & Warmup Schedule

It’s always a confusion for email marketers that How many IP(s) should we use and what is optimal email relay, daily or hourly limits for particular IP(s) & what is warmup schedule. It’s very hard to define, varying from customer to customer, especially customer's already built email marketing history, list size & quality of list. As per the detailed analysis of Sarv’s 20 Billion email relay, we found a conclusion as follows.

Warm up Process

IP Allocation and IP Warmup Schedule

It is important to note than this IP warmup plan is merely a way to help the sender identify potential weaknesses in their email program. Starting slowly gives the sender a chance to pause or slow down sending and adjust their strategy before their reputation is severely impacted. If client want to send emails from his own personal/business domain and don’t want to use our domain then it will mandatory to follow warmup process. Senders with a volume of more than 1Lac mails per day require the warmup process.

The number of IPs needed to accommodate your sending volume can change based on your type of sending, the domains you are using to send the mails and your sending reputation.

Ideal warm up schedules can vary greatly depending on a number of factors including: List age, list hygiene, spam reports, user engagement, domain reputation, content, domain distribution and many other factors.


Affiliate Marketing

It’s a process where other publishers and websites promote your business. If client do not use the primary domain of third party, then this is considerd as Affiliate Marketing.

Now if client will send affiliate mails then he/she need to follow the warmup process for secondary domain and primary domain also. This secondary and primary domain should not be used anywhere or do not have any mail history and it should be random. In case if client changes the domain due to blacklisting then he have to follow the warmup process all over again.

Also, if mails will get rejected from Gmail due to “Domain reputation” then client must have to change his/her domain.

Note:- Hard bounce ratio for affiliate marketing mails should be less than 3 percent.  


DNS Records Settings must be Prepared before we start Warmup

SPF (Sender policy framework): - Client will create SPF records in his domain control panel for the corresponding domain as is defined in user account.

DKIM (Domain key identification mail): - Client will create DKIM records in his domain control panel for the corresponding domain, which he will use for sending mails.

CNAME (Canonical Name): - Client will create CNAME for his mail-sending domain for tracking and return path.

PTR Records: - Client have to create the A records for the IP address which we will provide for mail sending domain. After creating the A records we will create PTR from our end.
MX Records:- Each sending domain must have a valid MX records.

A Records :- A & PTR records must be valid and related.

Now, if you are planning to use the dedicated IP, go ahead. This guide will help you make your IP crispy and warm at the end.
