Fullcontact vs SigParser

Fullcontact and SigParser are very different products but have some similarties. Here we’re mainly talking about their contact management toolset. You can use them together and we’ll show how they differ in this post.

You can use both

There is no reason to only use one of these tools. You can use both. If you’re already a FullContact user, you should try SigParser and see if you get a lot more contacts than you already had.

How SigParser and FullContact are Similar

Contact Database

Both build a contact database for the user.

Fullcontact is focused on contact records (Google Contacs, SalesForce…) where as SigParser is focused on finding contacts in email signatures.

Contact Sync

SigParser can sync contact updates out to other services but doesn’t overwrite any data.

Fullcontact has a much more advanced sync technology and is able to sync contacts between lots of systems.

How SigParser and FullContact are Different

If you want a full fledged contact warehouse for your team to share, with contact sync between multiple systems, use FullContact.

If you need to extract every contact you or your team has ever interacted with from your email system, use SigParser.

You can also export the results from SigParser and import them into FullContact or any other CRM system you might be using.
