For a new Email Subdomain, start ramping up each day as below:
Day 1: 25 emails
Day 2: 50 emails
Day 3: 100 emails
Day 4: 200 emails
Day 5: 400 emails
Day 6: 600 emails
Day 7 & onwards: Increase by 200 emails each day...
Send Emails from LeadStrive in an hourly Drip mode too
A good rule of thumb to follow.
Whatever Total Volume of Email to be sent in a day... Divide it by 10 (10 hours 8AM-6PM)
That will be your per hour drip rate.
