There's no mention of security, or the trust involved in outsourcing email workflow handling to you.<p>The interest for attackers isn't as high as something like LastPass, but <i>at a bare minimum</i> a successful hack will come back with a big list of valid email addresses and companies they have relationships with -- which would be very valuable to someone interested in spoofing, for example.<p>And that's assuming that the people/person behind mailparser.io are honest.<p>It depends on what kind of data your clients might want to handle in email workflow, but I imagine most businesses will be wary of passing off potentially sensitive material to an outside party that they don't trust. Things like "first month free" don't address this -- the fear isn't "we'll try this service and it won't work for us, and our money will be wasted", it's "we'll try this service, and an employee or hacker will sell our data to competitors, spam/upsell our customers, sell our contact lists...".<p>Obviously these aren't the most likely scenarios, but it's a bit like hiring a new employee who will be working <i>completely without oversight</i> with your company data... You'd want to put serious time into interviews, checking references, etc..<p>The site as-is: as far as I can tell, there are no human beings behind the site, or any established company. There's no phone number or address. It's not even clear what country (and hence legal jurisdiction) the business is operating in.<p>I don't mean to come off as too negative -- there are still companies that will not have a problem with the risks (and/or for whom the risks will be minimal), but you'll cast a wider net with a more solid presence.
