Inboxbooster, a San Francisco, CA-based tech startup that has launched from stealth to help emails reach the inbox and avoid spam, raised $1M in funding.
Backers included Y Combinator, and angels Francois Lagunas, Razvan Roman, Julien Lemoine and Ralph Gootee.
Founded by Nicolas Toper and Marcus Engene, Inboxbooster offers all businesses free unlimited email placement tests to help them monitor when an email is in spam, why and what remedial actions they can take to get their email into the inbox without hacking spam filters.
Built on a dataset of 100 million emails, Inboxbooster detects and fixes email in spam folders. Its resolution test initially confirms the issue by querying spam filters to understand what is wrong with the emails and then build a step-by-step guide such as removing specific words, changing the form of some URLs or steps to improve a poor domain reputation.
The tool also analyzes the delivery infrastructure and offers solutions, this includes evaluating the reputation of the domain and the sending IP while analyzing the content of emails to flag what part of the email is triggering the spam filter. Inboxbooster builds a personalized step-by-step guide to make emails compliant with filter requirements and get it back to the primary inbox.
It works with email senders, email service providers, marketing platforms to solve deliverability issues across Gmail, Outlook, Yahoo, etc.
Inboxbooster has over 2,000 customers including YCombinator, Zengo, and Wizbii among others.
