"Twillio SendGrid a Godsend"
What do you like best about Twilio SendGrid Email API?

I use SendGrid as my primary tool for managing sending and tracking mails with all the ecommerce and WordPress sites that I run. It's efficient, highly effective and simple to configure and work with.

What do you dislike about Twilio SendGrid Email API?

So far, I have yet to find anything that I truly dislike about SendGrid that I can vocally complain about. The setup with CloudFlare is a little manual and I'd say the only thing that could make it better is being able to export the values they want us to set and import them into CloudFlare or setting up an API key so that SendGrid just automatically does it.

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

SendGrid Email API solves my problem with setting up manual SMTP services on all my servers for WordPress where I can't always even access the backend. Using Twilio SendGrid email with WordPress SMTP plugin allows me to easily configure my mailers on all my websites that I deliver.

"Simple and Effective SMTP Relay Service"
What do you like best about Twilio SendGrid Email API?

SendGrid allows for SMTP relay of email from any location. After migrating to Microsoft 365, some legacy applications were unable to send email via Microsoft 365. SendGrid allows this at a very low price.

What do you dislike about Twilio SendGrid Email API?

I have very few complaints about SendGrid, but if I had to pick something, it would be that the service doesn't easily allow for multiple users in the same organization. This is a minor issue that doesn't negatively affect my opinion of the service.

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

SendGrid allows but Microsoft 365 and SMTP relay through servers hosted on Microsoft Azure. Our company has been able to continue using several applications that would otherwise need to be replaced without the services that SendGrid provides.

"Best software for Improving email Deliverability"
What do you like best about Twilio SendGrid Email API?

SendGrid is one of the best software for improving Email Deliverability using Email API. It is pretty straightforward software, which takes way less time to implement. Especially when you are using plugins like Memberpress, LearnDash, etc. on your Website, you would want to make sure that emails are delivered to the Client. SendGrid helps in making sure that emails really do reach inboxes. And, it is one of the most affordable software for sending Emails out there as well.

What do you dislike about Twilio SendGrid Email API?

None, except one small thing; sometimes when creating a sender profile in SendGrid, it doesn't load state names as per country i.e. if I select India as the country, it would still show me USA state names.

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

We used SendGrid for improving Email Deliverability for our Website using API. SendGrid Email API is easy to configure and comes in handy when you are using tools like Memberpress and other plugins that send out Emails from your Website install. I also implement it for almost every client for whom I develop Wordpress Websites to make sure emails for Contact Forms Submissions and Reset Password Request, etc. get delivered properly as well.

"Twilio is the best + they own SendGrid"
What do you like best about Twilio SendGrid Email API?

My product team has had a great experience with the Twilio and SendGrid API's. Their support does a great job and always has treated us well. My only regret is not buying stock back when we started using these two companies. We recently went to a multi-year contract with Twilio and got even better pricing then before. For our booking company Afton Shows and for our ticketing company, Afton Tickets, Twilio and SendGrid have been crucial to operations and we are thankful to have found them many years ago!

What do you dislike about Twilio SendGrid Email API?

Nothing. I have been super happy with everything from support, to pricing, to features.

"Main email API service we use for our CRM"
What do you like best about Twilio SendGrid Email API?

The setup of API was pretty straightforward, and the manuals were detailed. We have implemented integration with their API in our product in a few days, and it has been working fine for five years nowadays. We are looking forward to implementing other functions of this API in our software soon

What do you dislike about Twilio SendGrid Email API?

The free plan seems to change more often than it wanted to be, and some features of API are now being deprecated, so we needed to modify our software to reflect these changes

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

Sending emails through the CRM often conflicts with our providers' SMTP servers, so we needed to have an external API to implement proper communication with our customers. The benefits are also detailed reporting about the quality of our sent emails, unsubscribe functions, and detailed reporting
