Not from first hand experience but @dvassallo on twitter says how his audience is very organic, people unfollow and follow (equivalent of unsubscribe / subscribe I guess) all the time depending on the message he is sending and that's OK. If you have an user base that stops liking your content then maybe other users will start liking it and subscribe? Full disclosure I don't have much SEO experience and dislike the culture of selling people data and/or email addresses and/or optimizing for gathering more people. I feel that if your content is good and you're happy posting new updates it will either attract people or not and attracting people shouldn't be the end goal you optimize for but rather good content.
