Salesforce Marketing Cloud and Pardot (MCAE) IP Warming Best Practices – Improve Email Deliverability

IP warming is done by gradually increasing the email send volume; it might take 4-6 weeks or even more to gain a good reputation for your IP address. This can be gauged by regularly tracking the sent email engagement metrics. During the IP warm-up period, ISPs monitor whether you manage emails responsibly. It is a crucial rite of passage that every marketer has to go through!

What happens if your IP isn’t warm enough?

ISPs can become like Goldilocks. Not warming up your IP can lead to deliverability problems and emails being directed to the spam folder. Ouch! It can also take a lot of time and effort to build quality subscriber/customer interactions.

Best Practices to be followed during the IP warming period

• Ensure your authentication records such as SPF/SenderID and DKIM/DomainKeys are correctly configured and validated.
• Be compliant with laws like CAN-SPAM, GDPR, and CCPA by adding unsubscribe links, preference centre, email footer, and avoid spam words, etc.
• Use First-party data for sending initial emails during IP warming, to start with.
• Initially, start sending mails to your most active Prospects/Subscribers.
• Use the best email content that worked well previously.
• Track your email metrics regularly; if you see an increase in bounce rate, stop the process immediately and take action.
• Set and follow a structured email cadence.
• Clean up your email list based on the replies, unsubscribe, spam complaints, etc.
• Sending relevant content can improve your engagement rate, which can help to improve your IP reputation faster.
• Don’t suddenly increase your email volume.
• Verify the email address using the email verification tool.

IP Warming Strategies for Pardot

Salesforce Pardot provides an option to choose between shared and dedicated IP. If you are regularly sending emails to more than 100,000 emails per month, you can opt for a dedicated IP, and if your numbers are less than that, you can use a Shared IP. Shared IP doesn’t require any IP warming process. But that doesn’t mean a shared IP can improve your deliverability rate. If an account that shares your IP has underperforming campaigns it can adversely impact your deliverability rates as well.

Choosing a dedicated IP gives you more control over your sending reputation.

Before you can start warming your IP address, ensure you take care of these prerequisites. Here are some Pardot best practices for warm up:

• Allow the sending IP on your mail receiving server to receive test emails.
• Add SPF and DKIM to your DNS; make sure it’s verified.
• As said in the best practices section, segment your list with the most active prospects.
• It is also recommended to use First-party data for sending initial emails during IP warming.

IP Warming Strategies for Salesforce Marketing Cloud

The IP warming strategy for Marketing Cloud is different from Pardot. In Pardot, target audiences are business users and the database consists of business email IDs.

In contrast,  Salesforce Marketing Cloud has subscribers with email addresses from free email service providers like Gmail, Yahoo and Hotmail. The IP warming process also differs for both these industries. One is domain-based, and the other is a standard IP warming process which we saw earlier. Let’s see the Salesforce Marketing Cloud best practices for domain-based IPs.

It differs because of the database they have, and the B2C companies will majorly have their customer’s email address domain ends with aol.com, yahoo.com, hotmail.com, outlook.com, gmail.com, icloud.com, comcast.net, and more like that, because of which it’s easy to do a domain segmentation. In a B2B scenario, your customer’s email address will have their company’s domain, and you will not be able to segment. It is not mandatory to do an IP warming based on domain, but that is one of the best processes and allows you to build up the send volume quickly.

If domain segmentation is not possible with your database, you can still use the standard IP warming process.
