Hello @Avra,
Welcome to the Brevo community.
This topic has already been discussed a bit here:
The offer may be hard to read at first glance when compared to the free offer, but in fact, the free offer is pretty much only limited by the number of emails per day (which is already quite a limit), whereas for the paid offers, there’s both the question of the limit on the number of emails per month, as well as the limit on contacts which are more or less correlated.
Unless I’m mistaken (I’m just a simple user), any e-mail address entered in the contact list is considered a contact, whether or not e-mails are sent.
Perhaps someone from Brevo can correct me? Maybe @ahudavert ?
In your case, I think you’ll have to start with a 20,000 mails/month solution or more if you want to have at least 3,000 contacts, unless you don’t need to send more than 300 mails/day.
I hope this helps
