What it really is
A low-cost Chrome extension that adds tracking, mail merge and follow-up automation to Gmail.
Our take
Vocus.io is one of the cheapest ways to get tracking and automated follow-ups in Gmail, and monthly billing keeps the risk low. The limits on active follow-ups and snippets are tight at the bottom tier, and the Gmail-only support and dated site copy point to a small vendor. Use the 30-day trial to check deliverability and CRM sync before rolling it out to a team.
Why we rate it
Tracking, mail merge and follow-ups inside Gmail for $5 to $20 a month.
The catch
Gmail only, no free plan, and Basic caps active follow-ups at 50.
Best for
Solo salespeople on a budget
Founders doing light outreach from Gmail
Recruiters sending personalized follow-ups
Not good for
Outlook users
Teams needing a lead database or high-volume cold email
