subscribers

HI

My subscription plan is for 10000 subscribers. But I really don't know if that is too much or may be I need a subscription plan for a lower number. i tried to see on Contact management the total of my subscribers and it shows 70. But when I send campaigns, usually it goes to 1000+ of emails. So, i will like to understand exactly which will be a better subscription plan for me.

Thank you for your prompt  help.
