"Reliable and Scalable Marketing and Transactional email capabilities"
What do you like best about Twilio SendGrid Email API?

All-in one transactional and marketing email solution that appeals to both developers and marketers. Easy to integrate API triggers into external sites / apps and also easy to integrate with 3rd party marketing stack providers. Full suite of solutions from managing marketing lists to creating campaigns or transactional triggers. Category-based transactional reporting gives me lots of flexibility in how to roll up /aggregate reporting data. Robust activity exports out to other marketing stack tools for open / click / send based segments.

What do you dislike about Twilio SendGrid Email API?

I would like to see reporting developed out even further. e.g. more robust report data export options, more ways to slice and dice and analyze reporting data from the UI.

What problems is Twilio SendGrid Email API solving and how is that benefiting you?

Integrating a multi-layer marketing stack that leverages disparate data sources and tools to create a unified and robust customer communications and marketing platform. Great value for cost.

"Great if you are worried about deliverability. "
What do you like best about Twilio SendGrid Email API?

I've used Sendgrid for both marketing and transaction emails. It's less user friendly than other options but it's reliable and I trust their consistency with delivery. If anyone is having issues email delivery I always recommend Sendgrid for an easy solution to remove their headache. It's api means makes integration easy. It's very reasonably priced and would be great for smaller businesses with low budgets if they have a team to get it set up.

What do you dislike about Twilio SendGrid Email API?

It's not as user friendly as newsletter programs so I usually only recommend it to larger business or techy teams. The other occasion where I recommend them is if someone has repeatedly had issues with delivery because I think this is where Sendgrid shines. There is a larger setup barrier but this is generally worth it because all this setup means better reliability for your messages and campaigns.

What problems is Twilio SendGrid Email API solving and how is that benefiting you?

Email delivery problems! It also has great email marketing features that add confidence that your campaign will be delivered but it's not very user friendly as other newsletter programs.
