Ways to turn email signatures into contacts in 2026

Everyone who emails you puts their name, job title, company and phone number in their signature. You can copy those details into a contact by hand, use an Outlook add-in on one email at a time, or use a service that reads whole mailboxes. Here are the options we found, with what each one does, where it works and what it costs, from each maker's own pages. We make Sigbot, which is one of them.

All of them, side by side Outlook add-ins How to choose

The short answer.

Outlook doesn't read signatures for you, so for a few people you copy the details across yourself. Outlook add-ins such as Kutools, Email2Contact and Auto Contacts fill in the contact from the signature of the email you have open. To do a whole mailbox at once, SigParser reads Microsoft 365, Exchange and Google mailboxes and syncs to CRMs, and Sigbot reads Outlook and Microsoft 365 mailboxes into one shared list with iPhone and Android apps. If you already work in a CRM, HubSpot and Zoho CRM can fill in contact details from the signatures on the emails they hold.

All of them, side by side.

1. By hand, in Outlook.

Outlook saves a contact when you add one, but it doesn't read the signature for you. You copy the details across.

Every version of Outlook

Add the sender as a contact

  1. Open their email and select their name, so their profile card opens.
  2. Select Add to contacts (in classic Outlook, View more options > Add to Outlook Contacts).
  3. Copy their job title, company and phone numbers from the signature, then save.
What it's like

Free, and slow

  • Costs nothing and works in every version of Outlook.
  • Fine for five people; a long job for a few hundred.
  • Each contact stays as you typed it until you edit it.
  • The exact steps for each version: adding a sender by hand.

2. Outlook add-ins, one email at a time.

An add-in sits inside Outlook and works on the email you have open: it reads the signature and fills in an Outlook contact for you. Three that do this today:

ExtendOffice

Kutools for Outlook

Suits Windows users who want its other 100-plus Outlook tools too.

  • What it does: select the signature in an open email, then Kutools > Signature to Contact. A new contact opens with the details filled in; fix any field from its drop-down, then save.
  • Where: Outlook 2010 to 2024 and Microsoft 365 on Windows. Not macOS; its maker's separate add-in for new Outlook, Mac and the web has only its AI features.
  • Price: $59 for one licence, for life, with 2 years of free upgrades; 30-day free trial.
Celsios

Email2Contact

Suits people who add a few new contacts a day and want each one checked before it's saved.

  • What it does: its AI reads the signature and the email, you review the contact, and it's saved to Outlook. It can also add categories and notes.
  • Where: Outlook on the web, and Outlook on Windows and Mac with Microsoft 365.
  • Price: credits, bought in the add-in with no subscription; each extraction uses some, more for complex ones. 20 free credits to start.
Purposebuilt Systems

Auto Contacts

Suits anyone who wants their own Outlook contacts filled in, without an outside service.

  • What it does: Add to Contacts makes the sender an Outlook contact, with phone, job title, company and website from their signature. Contact Sweep goes through your sent mail and lists the people who aren't contacts yet, to add in bulk. It only fills in blank fields on existing contacts.
  • Where: Outlook on Windows, Mac, the web, iPhone and Android.
  • Price: free. Its listing says it collects no data.

Where the contacts end up: in your own Outlook contacts, so they're yours alone unless you share them (how to share Outlook contacts with your team), and they reach your phone through the Outlook app's Save Contacts or Sync Contacts (when that doesn't work).

4Team's Signature2Contacts does the same from text you highlight, at $12.95 to $24.95 per licence; its system requirements page lists Outlook 2000 to 2007, so ask 4Team about newer versions before you buy.

3. SigParser: whole mailboxes, into your CRM.

SigParser reads every email and calendar meeting in the mailboxes you connect and turns the people in them into contact and relationship data.

What it does

Contacts and relationships, for a CRM

  • Reads emails and meetings, signatures included, and scans the connected mailboxes daily.
  • One-off History Scans go back 1 to 10 years.
  • Exports to Excel or CSV, syncs to Google Contacts and Outlook Contacts, and from its Professional plan syncs daily with Salesforce, HubSpot and Dynamics.
  • Relationship data: who on your team knows whom, and which relationships are going quiet.
Where, and what it costs

Microsoft 365, Exchange and Google

  • Connects Microsoft 365, Exchange and Google mailboxes; IMAP mail is being phased out.
  • From $19 a month for one mailbox, billed annually; Team $49 a month for 3 mailboxes; CRM sync from $299 a month.
  • History Scans $99 to $249 per mailbox, once.
  • A free trial scans about the last 3 months.

Suits teams whose contacts live in a CRM, teams on Gmail or Google Workspace, and business development teams that want relationship data. How it compares with Sigbot, point by point: Sigbot and SigParser compared.

4. CRMs that read signatures: HubSpot and Zoho CRM.

If your team already works in a CRM, it may read signatures for you. These two say so in their own help pages. Both work on the emails the CRM holds, and fill in the CRM's contacts, not Outlook's.

HubSpot

Conversational enrichment

  • What it does: fills in job title, name, phone, fax and address from the emails logged in HubSpot, and can create new contacts mentioned in email threads. It's in public beta, and took over HubSpot's older setting that filled in contact details from email signatures.
  • Where: in HubSpot, with a Gmail, Outlook, Exchange or IMAP mailbox connected.
  • Price: HubSpot lists it with the Starter, Professional and Enterprise editions of its hubs, which are priced per seat. The older setting was listed for every plan, free included, until it moved into conversational enrichment on 25 June 2026.
Zoho CRM

Zia data enrichment from email

  • What it does: open an email on a lead, contact or account and click Enrich Data; Zia fills in the record from the signature, such as phone, job title, company and address.
  • Where: in Zoho CRM, with Outlook, Office 365, Gmail or any IMAP or POP mailbox connected.
  • Price: Professional edition and above, priced per user per month.

5. Sigbot: one list from your team's Outlook.

Sigbot reads the email signatures in Outlook and Microsoft 365 and turns each one into a contact: name, job title, company, phone, email and address.

What it does

A shared list, on your phone

  • Reads a whole mailbox, or everyone's on a team, and after the first scan checks each one by itself: daily on paid plans, weekly on Free.
  • On team plans you share folders, so everyone works from the same list.
  • The iPhone and Android apps add your contacts to the phone's address book, so calls show a name and company.
  • Exports to Excel or CSV. Newsletters wait in a review queue, and merges can be undone.
Where, and what it costs

Outlook and Microsoft 365

  • Works with Outlook and Microsoft 365, whichever version of Outlook each person uses. Not Gmail.
  • No CRM integrations, and it never writes to your Outlook contacts: it only reads mail.
  • Free plan, no card. Individual $19 a month or $190 a year. Starter $2,500 a year for 5 seats.
  • At work, IT usually approves it once, for everyone.

Suits teams that work in Outlook and want one shared contact list on everyone's phone, without a CRM; construction teams get a built-in Trade field and bid lists. More: how to turn email signatures into a contact database and caller ID from your Outlook contacts.

Questions.

Can Outlook turn email signatures into contacts by itself?

No. Outlook saves a contact when you add one, with the details you type in. To fill in a job title, company and phone number from a signature, you copy them yourself, or use an add-in or a service that reads signatures.

Which Outlook add-ins turn a signature into a contact?

Kutools for Outlook (Signature to Contact, in classic Outlook for Windows), Email2Contact (Outlook on the web, and on Windows and Mac with Microsoft 365) and Auto Contacts (Outlook on Windows, Mac, the web, iPhone and Android) each fill in an Outlook contact from the signature of the email you have open. From their own pages on 26 October 2026: $59 for a Kutools licence, credits for Email2Contact, and Auto Contacts is free.

Is there a free way to turn signatures into contacts?

Yes. Copying the details across by hand in Outlook costs nothing. Auto Contacts is listed as free on Microsoft Marketplace, and Email2Contact starts you with 20 free credits. Sigbot has a Free plan that reads your Outlook mailbox.

How do I turn a whole mailbox of signatures into contacts at once?

Use a service that reads the whole mailbox. SigParser reads Microsoft 365, Exchange and Google mailboxes and syncs to CRMs. Sigbot reads Outlook and Microsoft 365 mailboxes into one shared list, with iPhone and Android apps. Auto Contacts' Contact Sweep also goes through your sent mail and lists the people who aren't contacts yet.

Does HubSpot read email signatures?

Yes. HubSpot's setting for filling in contact details from email signatures moved into conversational enrichment on 25 June 2026. Conversational enrichment, in public beta, fills in details such as job title, phone and address from the emails logged in HubSpot, and can create new contacts mentioned in email threads. HubSpot lists it with the Starter, Professional and Enterprise editions (checked 26 October 2026).

Does Zoho CRM read email signatures?

Yes, in the Professional edition and above. Open an email on a lead, contact or account and click Enrich Data, and Zia fills in the record from the signature.

Which of these work with Gmail?

SigParser, HubSpot and Zoho CRM connect Gmail as well as Outlook. The add-ins work inside Outlook, and Sigbot works with Outlook and Microsoft 365 only.

Which ones keep contacts up to date?

The services that read whole mailboxes keep checking: SigParser scans daily, and Sigbot checks each mailbox every day on paid plans and every week on Free. HubSpot's enrichment works on the emails logged in HubSpot. The add-ins and copying by hand add or fill in a contact only when you use them.
