SigParser and Sigbot both read the email signatures in your mailbox and turn the people in them into contacts. They're built for different jobs. Here's what each one does, what it costs and who it suits. Every fact about SigParser comes from SigParser's own website and help centre, checked on 26 October 2026.
SigParser suits you if your contacts need to end up in a CRM such as Salesforce, HubSpot or Dynamics, if anyone on your team uses Gmail or Google Workspace, or if you want relationship data: who on your team knows whom, and which relationships are going quiet. It also scans calendars, and can go back up to 10 years of email in one paid scan.
Sigbot suits you if your team works in Outlook or Microsoft 365 and wants one shared contact list built from everyone's email signatures, on the web and on everyone's iPhone or Android phone, so calls show a name and company. It exports to Excel or CSV. It has no CRM integrations and doesn't work with Gmail.
SigParser's column comes from its pricing page, product pages and help centre, listed under Sources. Sigbot's comes from this site.
| SigParser | Sigbot | |
|---|---|---|
| What it's for | Contact and relationship data from your team's email and calendars, for CRMs, marketing lists and business development | One shared contact list built from the email signatures in everyone's Outlook, on the web and on your phone |
| Mailboxes | Microsoft 365, Exchange and Google (Gmail or Google Workspace). Other mail through IMAP, which its help centre says it is phasing out | Outlook and Microsoft 365. Not Gmail or other IMAP mail |
| What it reads | Emails and calendar meetings: headers, signatures and reply chains. You can also import address books, CSV files and CRM records | The email signatures in each mailbox: name, job title, company, phone, email and address |
| Older mail | The free trial scans about the last 90 days. One-off History Scans go back 1, 2, 5 or 10 years, with or without a subscription | The first scan reads the mail already in your mailbox. Or we do it for you: the Inbox History Build cleans one mailbox's full history, up to 50,000 emails, into an Excel or CSV file |
| New mail | Daily mailbox scanning on every plan | Checks each mailbox by itself: daily on paid plans, weekly on Free |
| Where the contacts go | Excel and CSV, and sync to Google Contacts and Outlook Contacts, on every plan. Daily sync with Salesforce, HubSpot and Dynamics from the Professional plan. Email marketing tools such as Mailchimp. An API on Enterprise | Sigbot's own list, in the browser and the phone apps. Excel and CSV export. No CRM integrations, and it never writes to your Outlook contacts |
| On your phone | Its site doesn't list a phone app. It syncs contacts to Google Contacts and Outlook Contacts | iPhone and Android apps: Caller ID sync puts your contacts in the phone's address book, so calls show a name and company; on iPhone it can label calls instead. Business-card scanning in both apps, and a map with a radius search around any site in the iPhone app |
| For a team | Team plan: top coworker relationships, custom fields and lists, advanced search. Professional adds relationship insights. An admin can connect many mailboxes at once through Microsoft 365 or Google Workspace | Team plans: everyone connects their own Outlook and you share folders, so the whole team works from the same list |
| Construction | A Construction & AEC page for general contractors, specialty subcontractors and precon teams: every subcontractor, owner and project partner from your team's email, and alerts when owners, architects and GCs go quiet | A built-in Trade field (UK trade packages or Canadian MasterFormat), bid lists by trade and area, and Copy emails or Email in Outlook for a selection |
| Cleaning up | Finds and merges duplicate contacts and companies. Email verification and job enrichment are add-ons, paid for in credits | Newsletters and no-reply mail wait in a review queue, and merges can be undone. Bounced addresses are flagged and left out of exports |
| Security | SOC 2 Type II from an independent auditor. Runs on Amazon Web Services. An on-premise parsing engine on Enterprise | UK company, ICO-registered, data stored in the EU. The Outlook app is publisher-verified by Microsoft and only reads mail. Not SOC 2 certified (Trust Centre) |
| Trying it | A free trial, no card: it scans about 3 months of mail and shows what it found. Exporting or syncing unlocks when you buy a plan | A Free plan, no card and no end date |
Prices in US dollars as each company lists them, checked 26 October 2026. Both can change; Sigbot's pricing page shows your own currency.
| SigParser | Sigbot | |
|---|---|---|
| One person, a year | $228Individual: $19 × 12 months, billed annually | $190Individual, paid yearly |
| Five people, a year | $948Team: ($49 + 2 × $15) × 12 months, billed annually | $2,500Starter: 5 seats included |
So paid yearly, one person costs a little less on Sigbot, and for a team of five SigParser's Team plan costs less than Sigbot's Starter. SigParser's Professional plan, the one with CRM sync, is $3,588 a year ($299 × 12), more than Starter. The plans include different things, so compare them on what your team will use.
Plainly, in both directions.
The SigParser column lists what its pages say it does (checked 26 October 2026). Where its pages don't mention something, we haven't guessed.
Both have a free way to try them on your own mailbox, so try the one that fits before you buy.
