Frequently asked questions

What is Followthrough?+
Followthrough is a Gmail extension that automatically tracks opens, link clicks, and replies on your outbound email, then sorts threads into two lists: Follow up (went quiet, needs a nudge) and Watching (a prospect engaged). It replaces manual follow-up tracking for sales reps and founders who don't want a full CRM.
How much does Followthrough cost?+
Followthrough is $19 per month per mailbox. There is one plan, and it includes unlimited tracked threads, automatic open/click/reply detection, and email support.
Do I need a CRM to use Followthrough?+
No. Followthrough works entirely inside Gmail and does not require a CRM. It reads your Sent mail and tracked links to determine which threads need follow-up, with no separate system to keep in sync.
Is Followthrough available on the Chrome Web Store?+
Not yet. Followthrough is in early access — new users join a waitlist and are onboarded directly while the extension completes Chrome Web Store review.
What Gmail permissions does Followthrough need?+
Followthrough requests standard Gmail API scopes to read and send mail on threads you explicitly opt into tracking. It never reads your full inbox and never sends mail without you clicking Send yourself.
Can I use Followthrough with a Google Workspace account?+
Yes. Followthrough works with both personal Gmail accounts and Google Workspace accounts.
How does Followthrough know a prospect replied?+
Followthrough matches inbound mail on a tracked thread against the prospect's email address and excludes automated replies (like out-of-office messages), so only a genuine reply clears a thread from your Follow up list.
Is Followthrough built for teams?+
Yes. Each team member connects their own mailbox and gets their own Follow up and Watching lists — there's nothing shared to configure, and pricing is per mailbox so teams can add reps as they grow.
