Here is what I would like to do:

I have database of 25000 contacts, from Linkedin.

I want to upload this into CRM them send messages from 5-6 addresses, each with a different course or service (one would be a gift box company).

I would segment and tag the different sublists, some may be overlapping.  

These are the addresses I would use:

grecolawfirm.com (my law office)

myfindersfee,com (a class I will offer on finders fees, with its own website and subscription)

englishforattorneys.com ( a series of classes with its own website and subscription).

Italytravelnetwork.com (travel website)

Italygiftbox.com (gift box website)

I am fine with a 1-2000 limit on messages to send per day.

'

If I am correct the CRM Enterprise level ($35/month, annually) will do this for me.  And, I can add subscriptions for around $60/month, after I have cleared 50k.

Please let me know if the Enterprise CRM plus Subscriptions are sufficient or if I need other add-ons like Campaigns or Contacts Manager.

My understanding is that the Plus account is limited to 5k contacts, and might have features I don't need.  

My usage profile will be infrequent transmissions generally, perhaps 1-2 times per year to offer a course or send law firm info.  There sill also be several small active lists for the course participants.

Let me know if I can do this generally (I am hopeful I don't need to buy a separate account for each domain).

Thank you and kind regards,

- Jay
