"Sophisticated and simple solution for email."
What do you like best about Twilio SendGrid Email API?

Easy to use API with php libraries to make development faster.

What do you dislike about Twilio SendGrid Email API?

API Documentation could be more detailed. Sometimes it's easier to figure something out through trial and error that should be clearly explained in the docs.

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

Improved email deliverability with minimal effort. Domain white-labeling is very straightforward. The new reporting makes it easy to determine why a customer didn't receive a specific email notification for transactional emails. It has also significantly helped with deliverability with our targeted marketing campaigns. We migrated from using Mailchimp to using SendGrid for marketing via the API, building our emails dynamically and have had great results with deliverability and customer engagement.

"Quick, Easy, Powerful Marketing Campaigns"
What do you like best about Twilio SendGrid Email API?

The Marketing Campaigns engine that SendGrid rolled out has a number of benefits for the business owner that doesn't want to get into API code. The Marketing Campaigns drag-and-drop editor is easy to learn and quick to navigate. After building your first campaign, you can easily duplicate it and not have to build each campaign from scratch. You get 2000 free contacts and once your business grows to sending more emails per month, you can upgrade. Nice feature for startups. The metrics are very expandable - you can view your open rate, clicks, and unsubscribes all in one screen. You can even drill down to what types of devices that your customers are viewing your email on. Keeping your contact list slim and clean is simple by viewing your bounces, spam reports, and invalid emails in a simple screenflow. Chop and drop or review your contacts for validity. So much more available, we would suggest you give it a try! Beats ConstantContact, MailChimp and other more costly, simple email creators - plus your emails won't carry their branding!

What do you dislike about Twilio SendGrid Email API?

We tried signing up for the Partners program to become an affiliate. We were directed to a simple contact form, filled it out, but never heard from anyone.

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

Email Marketing; the benefits are increased customer engagement, web traffic increase, and conversion rate of purchases has increased.

"Solid email service provider"
What do you like best about Twilio SendGrid Email API?

Sendgrid has a great, speedy, easy-to-use API for sending emails that's easy to integrate into any application.

What do you dislike about Twilio SendGrid Email API?

Setting things up for sending a lot of email can be confusing: setting up domains, keys, IP addresses, DNS entries, etc.

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

SendGrid allows our company to send hundreds of thousands of notification emails to customers each month. Speed and delivery are what's important to our users: getting the e-mails immediately, and in their inbox not a spam folder. SendGrid has consistently delivered on those needs year after year, and quite affordably!

"A robust transactional email provider"
What do you like best about Twilio SendGrid Email API?

Sendgrid has become my default mechanism for sending emails from applications. Rather than deal with the uncertainties of having an SMTP server available, and the headaches of network issues, its great to be able to configure my applications to just send this off to a service that does it all for me.

What do you dislike about Twilio SendGrid Email API?

It can be difficult to really get the answers you need when you need them with send grid because their UI has so much available to it. This is both a blessing and a curse. I am still getting a feel on my own for how to manage my processes better and take full advantage of what they have to offer.

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

I use Send Grid to send all my emails from my applications. Even those third party apps I setup that require an SMTP server, I can give them the credentials for a SendGrid SMTP. My own APIs make full use of the API. And while I use MailChimp currently for my email marketing, I am looking forward to trying out Send Grid when I have a change. My big plus with SendGrid is the presence of web hooks. I can, and have, configured email addresses to point to SendGrid and had a webhook then post that information to a webpage I have written for processing and storage. This is amazingly useful technology.

"2-year relationship"
What do you like best about Twilio SendGrid Email API?

The statistics and the numbers. And you can see a graph every day. it helps a lot.

What do you dislike about Twilio SendGrid Email API?

Nothing really, but maybe that they are focusing on marketing where some users are using it for other purposes.

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

We have a list of recipients, that is updated every week and we send them emails every day (5 or more). We track the bounced emails and other stats by SendGrid.
