What is the relevance of long subscriber’s list?

Make your subscriber list grow long but this does not guarantee you success. You can get contacts from the event, or you can ask for referral but when you are growing your list you should know who you are contacting, are they the right kind of people, will they be engaged with you, would they be interested in what you have to say.

A huge long list does not means success but the relevant one means your efforts of email marketing will not go in vain.
