Email recipients are unlimited on all three. The number is how many printed copies get mailed.
The yearly plan saves about two months.
One for every printed recipient, so everyone who gets a digest can write back. Kits come as a set.
This is where your monthly prompts arrive. It is how the whole thing works.
Pay attention here - while you may always opt out of texting, it is the main thing that makes this system effortless for you. Without text SMS authorization, all communications must be via email.
