I’d really appreciate it if you could help clarify the following:
Can I send follow-up emails within the same thread using email rotation?

Is it possible to receive replies on a different email address (i.e., set a different reply-to address)?

Can I turn off open tracking?

Can I fully control the sending limits for both sender accounts and campaigns?

For example, if I set the sending speed to 5 emails per hour and 20 per day per sender, and I add 5 sender accounts to a campaign of 100 emails — how will the sending be managed? Will the campaign be completed in about 4 hours?
