Where each fits
No single winner — pick for your team
MyComments.io
Its $29.99 Starter tier is below our entry price in raw terms. If you have very low comment volume, MyComments.io may be the cheaper place to begin.
ReplyZen
ReplyZen leans into sales-style AI replies with UTM and conversion tracking — a strong fit for advertisers who want to attribute revenue to comment replies.
ROAS Shield (ads-first alternative)
Every comment in the inbox shows campaign, ad set, and ad context. You can filter by campaign, see which ads attract spam, and tune rules per-ad. Generic comment moderators do not foreground which ad a comment is on.
