What is IP address warmup?

Your GetResponse Enterprise account comes equipped with one or more sending IP addresses that have never been used before. This means that they have no sending history. IP (or account) warmup is a process during which they earn their reputation with mailbox providers (MBPs). The MBPs need to see that you send relevant and permission-based emails before they begin to allow your bulk mailings through to inbox folders.

Your Account Manager will help you adjust the volume and frequency of mailings the first days following account activation. During the account warmup, it’s important to start with low volumes and send to the most active contacts first to start building a solid reputation. ISPs will analyze the number of factors your emails generate (e.g. spam complaints, user-unknown bounces, opens, clicks, “this-is-not-spam” hits). Based on the results, they’ll route the emails to appropriate folders.

Route fresh leads

When starting the IP warm-up process, it’s always best to start routing the fresh traffic from your websites to the new GetResponse Enterprise solution (this will require updating your signup forms). Organic list growth is highly recommended as it generates responsive and verified subscribers, especially if the subscriptions are processed in the double opt-in mode.

Follow the plan

Your Account Manager will give you a customized sending plan designed by our experts. They’ll tell you exactly how many emails you should import and send during the first 2 weeks to get the best results. You should import only those contacts who have been recently active, i.e. opened your last emails and/or clicked on the links. It is important that there are no bad addresses (incorrect or nonexistent) on this list.

We strongly advise you follow the warmup schedule. Avoiding it may lead to serious deliverability problems and can damage your reputation for a long time.

The plan below should work for most users, but we need to remember that there are many factors that can influence the warmup process. If the ISPs’ scripts determine that the quality of the generated traffic is below their expectations, they may block a part of the traffic or drive it to the junk folders. That’s why your Account Manager will monitor the results of your first mailings and update you on the progress of the warmup process. Depending on the results of the mailings, your Account Manager may suggest to slow down or to speed up the volume-increasing dynamics.

Here’s an example breakdown of an import batch that you should be importing daily during the first 5 days:

The day-by-day schedule should be as follows:
DAY 1: Email sent to ~ 2,850 contacts
DAY 2: Email sent to ~ 5,700 contacts
DAY 3: Email sent to ~ 8,550 contacts
DAY 4: Email sent to ~ 11,400 contacts
DAY 5: Email sent to ~ 14,250 contacts
DAY 6: Email sent to ~ 20,000 contacts
DAY 7: Email sent to ~ 25,000 contacts
DAY 8: Email sent to ~ 30,000 contacts
DAY 9: Email sent to ~ 45,000 contacts
DAY 10: Email sent to ~ 60,000 contacts
DAY 11: Email sent to ~ 80,000 contacts
DAY 12: Email sent to ~ 100,000 contacts

Once you reach the level of sending 100,000 emails per day, we will assess the results and advise you on the future tempo of growth.

Can I skip the warmup process?

The sending schedule we recommend is not mandatory. Yet, based on our experience, we know that sending e.g. 100,000 emails without building the IP reputation first frequently results in an IP block and temporary inability to deliver any emails to a particular ISP.
