Pointless company. Serves no purpose.
Unless you're willing to spend over $80 a month on a dedicated IP don't bother with SendGrid. They cannot send emails to Hotmail addresses.... You heard that correctly... IF YOUR CUSTOMER HAS A HOTMAIL ADDRESS, THEY WILL NOT RECEIVE YOUR EMAILS. That just seems insane for a business who's sole purpose is to deliver emails.
If that's not already a deal breaker, there also is no customer service. If your business is suffering because your emails aren't being delivered you will likely be waiting over 2 weeks if you hear back from customer support...
It's just an utterly useless business. Suitable only for people that can guarantee their customers will not use a Hotmail address and people who can go weeks/months without email if they happen to encounter an issue that requires customer support.
