Q: Questions Regarding SMTP Warm-Up for Custom Email Infrastructure

Hi Team,

I’m building my own email marketing platform and have multiple SMTP servers with dedicated IPs. I need a tool to warm up my SMTP/IPs by sending emails through my SMTP and interacting with my inboxes.

I have a few questions:

Do you use my SMTP for sending and my Gmail IMAP for receiving (like Instantly)?

How exactly does your warm-up process work (send, open, reply, mark important)?

On the lifetime plan, how many emails per account can be sent daily?

How long does it take to properly warm up new SMTP IPs?

Thanks!

A: Hi There,

The process you are describing is called split setup, and is an advanced technical setup that should be done by professionals.
Mystrika indeed support warmup and cold email campaign with split setup.

Yes, warm-up process mimick, exact human like behaviour (including sending, open, scroll, read time, reply and finally after a day move to warmup folder).

Please refer to the plan limit provided in bullet point for explicit limits. Most limits are at per email id level.
