In order to keep our email deliverability at a good state when running cold email campaigns, we should be able to put a daily sending cap to emails. Then equally distribute the leads to other emails to continue the campaign.

For example one account has these emails: name@domain.com, name.sur@domain.com, namesur@domain.com. Each of those will be sending 50 emails per day, and the distribution of the emails will be done equally between the three of those. So, that's 150 emails per day.
