"Great for transaction emails"
What do you like best about Twilio SendGrid Email API?

Sendgrid is very easy to set up and because it's such a popular and well known service, it can integrate with hundreds of different software providers, giving a lot of flexibility.

What do you dislike about Twilio SendGrid Email API?

If you don't know what you're doing, the idea of using a service like Sendgrid can be confusing to some people, and requires some time to figure out and integrate. This is not an issue with Sendgrid specifically, just with people who aren't fully understanding how the service works.

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

So I have my regular email service provider where I send my newsletters, promos and such but they're not so good at sending transaction based emails. Sendgrid solves that problem for me.

"Email software that works best"
What do you like best about Twilio SendGrid Email API?

To use in several of my websites, I wanted an email API. It's what I use for transactional emails as well as for our email marketing business. All of the features were created by us, and the Twilio SendGrid Email API is compatible with it. It's simple to set up and maintain, and there's plenty of documentation to get started with.

What do you dislike about Twilio SendGrid Email API?

The installation of this software was quite complex and time-consuming. We had to contact the support service several times before we were able to get the system up and running.

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

We needed some sort of good software for an email campaign, and SendGrid came through for us. With the help of SendGrid, we are able to run various marketing campaigns, and it is also a very organised software to utilise.

"Good features but expensive for basic usage"
What do you like best about Twilio SendGrid Email API?

1. Reliability - Its uptime is pretty excellent and gives me the confidence to send bulk emails without any fear at anytime. 2. Templates - It comes with a sound library of templates that I customize with my data and save for future usage. 3. Analytics - Its monitoring dashboard helps me understand my customer experiences, and I can pull in this data externally for further analysis.

What do you dislike about Twilio SendGrid Email API?

1. High Price - It has been heavily rising its prices, which I find difficult to comprehend. I might choose other alternatives since my use-cases are not as complex. 2. Long Support Wait Times - Even for an upgraded package, the support is not real-time and you have to wait till a long time to get in contact with a real-person.

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

We use SendGrid APIs in our platform for all end-user communications via SMS. Since we operate at scale with complex developer requirements, we chose SendGrid over other vendors. It's reliability and heavy customer-focused features are the primary reasons for my overall positive review. However, the pricing model is pretty expensive and wouldn't recommend for others who might not need all the advanced features.

"Sendgrid - The most easiest API for sending emails"
What do you like best about Twilio SendGrid Email API?

The best thing about Twilio Sendgrid API is the ease of setup. First, when I created an account with Sendgrid, the steps to integrate your existing email server with Sendgrid Email API is very easy. Very few parameters like the API ID, password and username provided by Sendgrid need to be configured into the existing SMTP server and its done. Moreover, you can use the Sendgrid API flexible plans with plans as low as 15$. One more useful feature is the Usage Alert which is sent as an email. So you know, how many emails you have already used up and can accordingly plan the remainder of the month without increasing your monthly bill.

What do you dislike about Twilio SendGrid Email API?

Most of the features provided by Sendgrid are useful for detailed analysis and further action. Nothing which I dislike as such. Only thing which I like to mention was the increase in pricing of plans which happened when Sendgrid merged with Twilio. However, we have absorbed the increasing cost over the time period.

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

I am using Twilio SendGrid Email API to send emails to a large list of prospective customers on behalf of my client. Generally, I am sending upto 10000 emails on a daily basis, and the performance of Sendgrid servers is quite good.

"Fastest Integration I Have Ever Done"
What do you like best about Twilio SendGrid Email API?

Twilio SendGrid has a very to use API which allows you to get up and runninng in minutes. I can also get to enforce which email addresses can send from my API key and this is a major plus for control and security. The free 100 email per day limit is also very ideal for testing.

What do you dislike about Twilio SendGrid Email API?

I hvave not come across any of these yet.

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

This API has really helped with customer onboarding and email verifications. SendGrid is very reliable and we use it for all our email comms in our apps

"Email API made easy"
What do you like best about Twilio SendGrid Email API?

It was a super easy setup process from an engineering perspective. All you need is to make an API call and you're set.

What do you dislike about Twilio SendGrid Email API?

I think the visibility into deliverability could be improved. Sometimes it's tough to understand when recipients are opening their emails fully.

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

We used to deliver our emails via our own application server, so using an external service sped up our platform.
