How we picked
The whole point of a Gmail-sidebar CRM is that reps never leave the inbox, so we judged these tools on how complete the in-Gmail experience actually is. We weighted render depth (does the full CRM live in the sidebar, or just a contact card?), automatic email and meeting logging, Google Workspace breadth beyond Gmail into Calendar and Drive, and pipeline actions you can take without opening a separate tab. A CRM whose sidebar only shows a contact's name — forcing you back to a web app for everything else — failed the test.
What to consider
- You want your entire CRM inside Gmail → NetHunt. Records, deals, and email campaigns all render in the sidebar; it's a CRM that happens to live in your inbox.
- You live across Gmail, Calendar, and Drive → Copper. Google's officially recommended CRM feels native across all of Workspace, not just email.
- You hate manual data entry → Salesflare. It auto-fills contacts and logs activity from your inbox, calendar, and LinkedIn.
- You need a free option → HubSpot, whose free Gmail extension covers tracking, templates, and contact context.
- Relationship-led, not pipeline-led → Folk, the lightest sidebar for teams managing partnerships and warm intros.
Pricing snapshot
This category skews mid-priced. HubSpot and Folk both offer free tiers (Folk paid from $20/mo). Salesflare starts at $29/user/mo, NetHunt at $30/user/mo, and Copper lists a $9/user/mo Starter but most teams land on the ~$59/user/mo plan to unlock its real workflow features. Annual billing typically shaves 15–20%.
How deep the Gmail integration actually goes
There's a spectrum here worth understanding before you buy. At the deep end, NetHunt and Copper are architected around Gmail — the inbox is the primary interface, so adoption is effortless because there's no second app to open. In the middle, Salesflare uses the sidebar to surface auto-captured data while keeping a standalone app for reporting. At the lighter end, HubSpot and Folk treat the sidebar as a convenient window into a CRM that primarily lives elsewhere. If your team genuinely never wants to leave Gmail, choose from the deep end; if the sidebar is a nice-to-have on top of a broader platform, HubSpot's free extension is the pragmatic starting point.
