IP Warm-up Process: Why is it Crucial?

Every time you add a new IP address to your account, it is referred to as a “cold” IP because it has no history with Internet Service Providers. You must increase your email sending volume and adhere to a set schedule in order to warm up your IP and establish a reputation. Even if you have completed the warm-up schedule process before, you will need to do so again if your IP has not been used to send for more than 30 days.

How do you get from cold to warm?

1. Content
Sending quality material from the start is crucial if you want to establish a solid reputation and secure trouble-free inbox placement. You should never email any potentially questionable content because reputational harm might be almost permanent.

2. List Quality
Avoid buying email lists as they cause your IP to be blocked and ISP flags, since user interaction, increases ISP trust and produces the greatest outcomes for your email deliverability. Send emails only to subscribers who opted in using your single or double opt-in process (preferred).

3. Steady volume
ISPs sometimes perceive large spikes in email traffic as spam, so it’s critical to maintain a consistent email flow to establish your reputation. Rather than sending out 35,000 emails all at once, you can accomplish this by adhering to the timeline listed below. Since email monitoring systems often only analyse the most recent one to two weeks, this habit needs to be maintained. If you break your sending pattern, you’ll be back where you were and have to start over.

4. First Email Campaign
Internet Service Providers will start compiling and combining your reputation data as soon as you send out your first email campaign. They will consider bounces, grievances, openings, and clicks. As we’ve previously discussed, it’s critical to begin your initial emails with your best campaign content because this is the period of time that will positively affect the sending domain and IP address. This also implies that it’s crucial to send messages to the users who are most interested first. These are the subscribers who have just opened or clicked on your newsletter, or who have just subscribed via the double opt-in method.

5. Feedbacks
Building your reputation by responding to ISP feedback and complying with their requests demonstrates your willingness to work with them. Following these email delivery best practices will make the difference between your message reaching the recipient successfully and it ending up in the spam bin.

Responsible for ramping up your volume

Your strategy for the warm-up schedule process will have a significant impact on how ISP monitoring systems label your IP address because a quick and unexpected huge volume approach results in blocks and rate limitations. By choosing a cautious strategy with modest volume increases, rate restrictions and blocks will only apply in cases where interaction is low, the complaint rate is excessive, there is poor content, or a low-quality email list is being used.

Our effective Warm-up Process

You may find our basic IP warm-up strategy below. A few things to remember are:
Make sure to spread the volume across several Internet Service Providers while choosing it. Start with the subscribers who are the most active, ideally openers or clickers over the past 30 days. The maximum hourly restrictions for the warm-up plan time, based on 2 IPs, are shown in the table below.

How should you plan for the warm-up schedule?

Due to the simple fact that larger ISPs sometimes prevent traffic few weeks, your initial campaign may have some difficulty reaching customers. Reaching your consumers’ inboxes depends on sticking to your plan and taking the ISPs’ advice. If you adhere to your plan after the first few weeks, the majority of the roadblocks will disappear, giving you a solid reputation.
