I use SendGrid for sending communication and marketing emails to thousands of customers every day. Sending close to 100,000 emails per month and the quality of service is quite good. Must say I am happy to use SendGrid.

The best thing about using the SendGrid Email API was the performance measured in terms of email deliverability and server uptime. The dashboard provides good insights with respect to number of emails sent, delivered and opened. Thus helps a great deal in improving marketing campaigns. From the deployment point of view, the integration of SendGrid with the existing email service was quite easy and can be completed easily without great efforts.

As far as technical aspects are concerned, there is nothing which I don't like. On the pricing front, would like to add my views. Currently, the pricing plans are available as Free (100 emails per day), Essentials and Pro. The Essentials plan starts from 14.95$ per month for upto 40,000 emails a month and the Pro starts at 89.95$ per month. These plans are good for small and medium size websites. Would be good to see if a new Basic plan is introduced for a low starting price of 4.95$ per month and offering upto 10,000 emails a month. Such a plan would be highly suitable for extra small website applications who have a limited customer base.

Reliable, excellent delivery rates, clean API - I like 'em. Have used for years including Pre-Twilio acquisition, and still good service.

No complaints here. Not sure what to write.

I really enjoy having Sendgrid in my toolbox of things to enhance my business

Send has been an asset in my business to help me get better email deliverability in my marketing campaigns

For me, it took a few minutes to get it going in the way I use it, but wasnt too difficult

What a horrible experience. After signing up as a new business customer as part of a new marketing strategy my business implemented, SendGrid immediately suspended my account for no reason (after taking my personal information), and an agent then proceeded to tell me some magical 'vetting' system determined I wasn't eligible to use their service.After asking how an earth they could 'vet' me considering they haven't even obtained anything about my business they proceeded to tell me they can't tell me why and that their decision was final.Appalling service, I genuinely have no idea how these people even have customers to begin with if one can't even sign up....

Absolutely nothing, couldn't even sign up...

Everything, because they discriminate on who signs up to them, and give no explanation for suspending your account after taking your personal information.
