Hey Everyone!

I was reading the Litmus blog post; "*Tips for Email Agencies: How to Coach and Train Your Clients on Deliverability*" by Bettina Specht and I saw the section; "IF A CLIENT HAS DELIVERABILITY ISSUES, WHAT STEPS WOULD YOU RECOMMEND TO FIX THEM?". I was wondering if anyone knew where I could find the directions on how to re-warm an IP address?


I have been searching and I can find everything on warming a new IP address, but I wanted to know specifically for one that has already been used.

Thank you in advance for your assistance!
