"We went from a database of zero contacts to 143,000 overnight! We have some of our team traveling to Brasil for a convention and we wanted to reach out to our contacts their, without SigParser we would have been lost on how to find those contacts. Not only did we set up several meetings, we received a contract!"

"The primary benefit we've experienced is enormous time savings from data entry. In a few moments, the software identified multiple contacts and organized the data so that we could easily upload it to our CRM. In our work, these contacts are our primary asset. SigParser is built on a sound idea - spend time connecting with your contacts as opposed to cataloging them. Let the software do the legwork."

After attempting to connect both mailparser.io and Zapier's own Email Parser, we have concluded that SigParser is the best product on the market to connect to our CRM! Their customer service team was a great help in getting our subscription started.

"I like the 25% new contacts we get from accounts that my team and I work with. Typically data attrition causes a net loss of 20% of all business contacts per year, with SigParser, or database is actually growing due to up to date contact information being added from auto replies and signature lines on all of our marketing and sales activities. We also see 17% more direct phone numbers added to our CRM, 11% updated titles, and 12% more cell phone numbers. The contact update and organization is the best feature. The next best feature is metrics and reporting on all inboxes that you hook up for your team. You can see their volume and performance within email. This is particularly valuable for sales managers. Lastly, I appreciate that you can slice and dice and create reports based on user contacts that are frequently emailed, and prepare lists based on the best performing segments of your business email outreach. As a marketing agency this is one of the best tools I have come across during my 12 years in business."

"SigParser is a life saver!

It works quietly in the background of my CMS, working hard to accurately scrape valuable contact details from emails we receive. It's been amazing how many times I've been able to contact a prospect immediately without having to hunt around for their contact details - it all just works. "

Genius tool that allows me to extract contact details and manage my contacts in a far better way than Google contacts. great job!"

"A CRM is only as useful as the data it contains, and SigParser offers a quick and easy way to bolster that data by crawling emails for missing data points. It's just getting started, but the founders are easy to work with and I can see this developing into a must-have app."

FAQ: What languages does SigParser support?
SigParser has the best support for English. The next best language is German. Then it has good support Spanish, French, Portuguese, Russian and Dutch.
FAQ: Can email addresses be found in forwards?
Yes, SigParser is the only product we know of that can extract email addresses and contacts from a forwarded email or a reply chain of emails.
FAQ: How many contacts can SigParser find?
On average, SigParser finds about 7400 contacts for the most recent year depending on your type of business. But if multiple mailboxes are connected and longer time periods are scanned SigParser can find 100K+ contacts.
