"Thoughtful and diligent team, intuitive product "
What do you like best about Twilio SendGrid Email API?

Tim, our account manager! If you speak to another ESP, any question you have often results in a long, seemingly incomprehensible article thrown at you. SendGrid is consistently there to help-with thoughtful explanations, simple instructions, and smart recommendations. An example - SG has technically have no obligation to explain all the nuances of deliverability, or QA a big send alongside our team (etc.) but they go out of their way to do so knowing how that information empowers our team to make smart decisions.

What do you dislike about Twilio SendGrid Email API?

I'm using the marketing tool right now, and there's a lot of things it can't do yet that I'd love for it to do - to be able to export my opens, to not have the code random CSS now and again, to have an FTP or an easier way to import large files than a CSV, etc. Because we've really appreciated our customer service / account management to date, we wanted to give SG a try with our marketing sends. But I think we're not the ideal use case for the tool.

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

We have a small, lean team. We really appreciate pairing with the experts, who don't mind working so closely with us.

"The dashboard shows everything needed and the spam and bounce service is great."
What do you like best about Twilio SendGrid Email API?

The great HTTP and API integration. The nodeJS module provided is easy to use and integrate seamlessly with other modules. For instance, we are currently using the node, python and HTTP APIs to integrate our main application, a server process and a hybrid mobile app.

What do you dislike about Twilio SendGrid Email API?

The need to inform an address and the time for them to validate can take a while, but is nothing really long and other products also do that. Other than that there is not much that i dislike since after setting it up, it works great.

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

Login, Password recovery and some other transactional e-mails. After using the product "template maker" users interact 2 times more than before.

"Twilio SendGrid: Empowering Seamless Email Communication"
What do you like best about Twilio SendGrid Email API?

First and foremost, the reliability of Twilio SendGrid is unmatched. The API ensures that emails are delivered promptly and consistently without the hassle of managing complex email infrastructure. With Twilio's extensive network of servers, emails are sent efficiently, minimising the chances of them ending up in spam folders or being undelivered altogether. Another standout feature is the scalability of Twilio SendGrid. Whether you're sending a handful of emails or running large-scale email campaigns, the API effortlessly handles the workload. This scalability is particularly valuable for businesses that experience fluctuating email volumes or those planning to expand their reach in the future. Moreover, Twilio SendGrid's email customisation options are impressive. From designing visually appealing templates to personalising content based on user preferences, the API allows for seamless branding and targeted messaging. This flexibility ensures that each email feels tailored to the recipient, enhancing the user experience. Lastly, Twilio's commitment to security is evident in the comprehensive measures implemented within the SendGrid Email API. With features like authentication, encryption, and SPF/DKIM validation, users can rest assured that their emails are protected from unauthorised access and spoofing attempts.

What do you dislike about Twilio SendGrid Email API?

One aspect that could be improved is the complexity of the initial setup process. Setting up Twilio SendGrid Email API requires some technical expertise, and the documentation provided could be more beginner-friendly. Simplifying the onboarding process and providing more intuitive resources would greatly benefit users who are new to the API. Another area where Twilio SendGrid Email API falls short is in its email template editor. While the API allows for customization, the template editor lacks advanced features and can be somewhat limited in terms of design capabilities. Enhancing the template editor with more intuitive drag-and-drop functionality and a wider range of pre-designed templates would make email creation more efficient and visually appealing.
