Email Parsing FAQ
This isn't finding the signature? Why?There are two primary reasons SigParser doesn't detect a signature for the email you pasted in above.
- Encoding issues: The email might be text but you checked the Is HTML checkbox or the opposite. The email might also be MIME encoded still.
- Signature ownership: The Sender Name and Sender Email Address fields don't match the contents of the signature. SigParser is most concerned with assigning right signature to the right email address and skips any contact data it isn't confident about.
The easiest way to really see how well the SigParser API will work is by forwarding real emails to firstname.lastname@example.org. You'll get a response within seconds.
The other way to try SigParser is just to create a free account and we'll do a free 90 historical extract of your email account. We'll build you a database of contacts in minutes. You can then see how accurate we are. We use this exact same API on our backend to drive our core product.
How do I get a key?Signup for a SigParser account. You can just use a username and password to create the account. Then generate a free API key on the API Tools page. You'll get more than 1000 requests per month for free. If you need more, contact us and we can discuss your requirements.
The phone number wasn't detected...SigParser has a lot of rules to validate phone numbers. If a phone number doesn't look correct or maybe the phone number isn't in the right context then it won't capture it. SigParser is most concerned with not getting contact data wrong over getting every last value.
This doesn't work as well as Talon/MailgunMailgun demos better because it finds every signature plus lots of stuff that isn't a signature. It can split emails but Talon by Mailgun is okay with being wrong a lot more often. It also only works for English emails and English email dividers. Once you start processing email for a real business you'll see email dividers for many emails are in different languages.
SigParser on the other hand is focused on highly accurate contact discovery and splitting emails in order to achieve that. SigParser will opt to not capture a part of a signature if it isn't confident the signature is actually for the sender of the email. It also supports a growing list of email languages.
How accurate is your parsing?Very accurate. We've validated our results with thousands of mailboxes across hundreds of organizations. Our users care about accuracy and so they submit any errors they find. If you find an error submit it to us and we'll have a fix out within a few days generally.
