Majorly, there are 5 Fundamentals for Warming up your Domain and IP which are as given below,


1. Send emails daily and scale gradually


It is important to scale your emails gradually. At Pepipost we leverage our warm-up process for new customers or new IPs, sending a small chunk with a warm-up process spread across several weeks.


2. Send to the most active/engaged email addresses


Put your best foot forward when starting with new IPs. Start by sending emails to your most engaged users or the loyal ones who interact regularly on emails you send them. Most ISP's rate reputation on interaction with an email. Your most engaged or active users will open and click your emails more; the chances of you reaching higher volumes sooner is promising.


3. Send your best (as in best performing) content


Send your best and most engaging content. Consider emails like welcome emails, account notification emails and other transactional triggered emails that draw the highest open rates


4. Ensure suppression is real-time


Unsubscribes, hard bounces and abuse complaints should be suppressed immediately. CAN-SPAM Act 2003 says unsubscribes should be honoured in 10 business days. Folks, it's 2017 and today if we still take 10 days to suppress an unsubscribed user, then be ready to get a massive storm of abuse complaints.


5. Monitor and act


Carefully monitor email spikes and performance like the stock market. Decide whether it is a good time to go to the next level or continue with current email volume till performance is better. Ensure during this process that your email bounce rate is less than 1% and abuse complaints are close to 0.

While all the above fundamentally lays a good foundation for warm-up, one has to also ensure that they have authenticated their domain via SPF, TXT, and DKIM.


Remember warming up IPs is a long process and requires lot of monitoring. Like the Narrator says in Star Wars (The Clone Wars, Season 2) “The first step to correcting a mistake is Patience”. Ensure you have enough of it to continue until your email is stable. Good luck!
