Best Gmail CRM tools in 2026 (compared)
The best Gmail CRM is the one you open on a Tuesday. Here is how Streak, HubSpot, Salesforce, a spreadsheet and KanbanMail actually differ.
Search “best Gmail CRM” and you get two kinds of lists: enterprise suites that happen to have a Gmail sidebar, and Chrome extensions that promise to turn your inbox into Salesforce. Most of them are honest about features. Few are honest about the job: see your deals without leaving the mail you already live in.
This comparison is for people who close in Gmail — freelancers, small teams, founders — not for a 40-seat RevOps rollout. We make KanbanMail, so we will say so. We will also say when you should pick something else.
The short version
| Tool | Best for | Lives in Gmail | Reads the mailbox | Price (typical) |
|---|---|---|---|---|
| KanbanMail | A personal Kanban of deals you choose | Yes — full board | No. You send the thread. | Free |
| Streak | Pipelines plus mail merge and boxes in Gmail | Yes — deep Gmail UI | Yes — Gmail add-on with pipeline data | Free tier, paid seats |
| HubSpot Sales | Logging mail into a full CRM you already use | Sidebar / tracking | Yes, if you connect the inbox | Free CRM; Sales Hub paid |
| Salesforce Inbox | Teams already standardized on Salesforce | Sidebar | Yes — syncs to Salesforce | Salesforce licenses |
| Google Sheets | A forecast you update once a week, on a good week | No | No | Free |
Streak
Streak is the default answer to “CRM inside Gmail,” and for good reason. Pipelines, boxes, snippets, mail merge: it is a real product with years of Gmail UI work. If you need send-later campaigns and shared boxes for a small sales pod, start here.
The cost is weight. Streak asks for Gmail access, has more surface area to learn, and the paid plans show up when you outgrow the free box. If all you wanted was columns and a value, you will spend the first hour turning features off.
See also Streak alternatives if “simpler / cheaper / less access” is the search you typed.
HubSpot (Sales Hub + Gmail)
HubSpot is a CRM that visits Gmail, not a CRM that is Gmail. The extension logs emails, shows contact panels, and can track opens. That is the right design if marketing, deals, and a knowledge base already live in HubSpot.
It is the wrong design if you do not want a second system of record. Empty HubSpot portals are a genre. If you will not live in HubSpot, do not use Gmail as a loading dock for HubSpot.
Salesforce Inbox
Same pattern, heavier. Salesforce Inbox makes sense when your company already measures you in Salesforce stages. It does not make sense as a first CRM for a consultant with 20 conversations. You will feel the admin before you feel the pipeline.
If you are one person who sells by email, you do not need Salesforce. You need columns. We wrote that argument down in spirit in how to use Gmail as a CRM.
The spreadsheet next to Gmail
A Sheet named “Pipeline 2026” is honest until Friday. Columns: name, email, stage, amount, last contact. You copy the sender from Gmail. You forget to update the stage after the call. By month two the Sheet is archaeology.
Spreadsheets are good at sums and bad at “open the thread.” A Gmail CRM should not make you retype the customer.
KanbanMail
KanbanMail is a Chrome extension (and a Gmail add-on) that puts a Kanban board inside Gmail. You pick the email. It becomes a card: company, value, expected close, next step, notes, link back to the thread. Columns are yours.
What we do not do: scan the mailbox, create Gmail labels for you, or hold Gmail API scopes on the server. Login is Google profile only. That is a product choice — less magic, less data.
Pick us if you want a board you will actually drag, for free, without another CRM religion. Pick Streak if you need merge and shared boxes. Pick HubSpot or Salesforce if the rest of the company already lives there.
How to choose in five minutes
- If a VP already bought Salesforce or HubSpot, use their Gmail plugin. Do not fight the system of record.
- If you need mail merge and team boxes in Gmail, look at Streak first.
- If you need a personal pipeline and you hate empty CRMs, install a board in Gmail and put ten real deals on it today.
- If your current “CRM” is a Sheet, move the live rows onto cards and delete the Sheet after two weeks of truth.
A Gmail CRM is not a feature list. It is a habit. The 2026 winner is the one still open next to your inbox in November.
