Yesterday my dad passed away. Today, when I am mourning and consoling family members, I start receiving numerous calls from customers who have not received emails that are normally triggered by Sendgrid. These calls couldn't have come on the worst day of my life! I have to do research and try to figure out what was going wrong. Then I find out that SendGrid has put my account on hold. No notification emails, no telephone call....nothing. Then to try and contact customer service is a nightmare. It a we will call you, just leave your telephone number. I find out it's because SendGrid's security has been breached and I have to add more security and reset my account! SendGrid has had poor customer service in the past, but this is the last straw. Do not use this company if you are looking for a stable service with good customer service!
