I'm trying to schedule a newsletter and I am "narrowing by tag" and I am unable to add more than 10 tags. After I select 10 tags, the remaining tags get greyed out and I can no longer select additional tags. Is this something to do with plan tiers? I can't see any supporting documents on tags that address a Tag limit per email. If anyone is familiar with this Narrowing By Tag tag limit, please help. Thanks.
