I have been warming up our domains using lemwarm And it shows we can start campaigns now(after 15 days). A quick question - daily email limit is on an individual email or domain? For example if have abc.com domain - email limit is let's say 50 per day prafful@abc.om praffulgoyal@abc.com will have combined limit of 50 or combined limit of 100?

50 as per my understanding

limits will be per mailbox/email

Not an expert, but i would think sending limits are usually at the sending domain(ESP) . limits on individual emails are using set up by CRMs/Tools to move you up the ladder.

no consensus so far, any more experts who have researched this before i asked gpt, here's the response

The suggested emails per day is 20 per day (at email level), and it's suggested to have 3 emails per domain (60 emails per day per domain). Have been sending cold emails for a few months now, our consultant sends 1.5 million emails per month. Do not send 50 emails/day from a single email, otherwise your emails will be suspended very soon.

@Shubham Sahu is right. stick to 20 emails per inbox and 2-3 inboxes per domain. Also ensure you are doing ESP matching. If you can, avoid outlook for the time being and only send to google inboxes or smtp ones.
