This is usually an invitation sent out to the whole mailing list. If your company is holding some event, such as a physical reveal of a product, or a webinar, this is the starting point that will significantly increase awareness. This is a mixture of a newsletter and offers email, as people are asked to participate in the event that they can either only watch, or make a purchase as well.
On the flip side, Aweber’s method of managing followup emails allows me to know exactly which subscriber has received which follow up emails and when. With MailChimp, I really have no clue who has or hasn’t received a particular email. Overall, I kind of prefer Aweber’s method of managing follow-ups but it is basically a wash depending on your preference.
Think about implementing referral links to incentivize your subscribers to spread awareness about your brand, too. Referral links allow your current customers to promote trackable links for your business. In exchange for sending new paying customers your way, you can give them incentives like discounts, coupons, vouchers, cash, prizes or redeemable points.
