Q: How many inboxes can we warmup?
Is there a limit to the numebr of inboxes we can warmup? I have 120 inboxes and I need them all warmed up before sending emails. Can I warm them up with Tier 1 code? (Only warmup, not sending)

Thank you for choosing Mystrika to help grow your business.
Yes, you can do that one tier 1.
Thank you. How good is your warmup feature? I read reviews saying that the warmup feature ruined their deliverability, but I don't want to take that at face value. I'd like to hear from you. Thank you
We have a wide range of folks using Mystrika. At one point, we had to put an agreement before customers added their email to make them understand what warmup means. And 3-4 people out of 7500+ users is like what? 0.05%? We think that's a great standard.
All we can say is our warmup pool is best in industry. So much so, that our competitors are copying our warmup pool strategy and enforments.
