Yes - you can run as many campaigns simultaneously as you need.

Simply create a new campaign in Prospi and launch it alongside your existing one.

If two campaigns are using the same email accounts, those accounts will split their daily sending capacity between both campaigns. For example, if an account sends 50 emails/day and it is in two campaigns, each campaign gets roughly 25 emails/day from that account.

To avoid splitting capacity, you can assign different email accounts to each campaign using inbox rotation settings. This way each campaign has its own dedicated sending accounts and full capacity.

There is no hard limit on the number of concurrent campaigns in Prospi.
