"Twilio's Sendgrid: A perfect service for your marketing campaigns"
What do you like best about Twilio SendGrid Email API?

The best feature would be the high delivery rate compared to similar services. The implementation is also easy as well using the documentation provided for most popular languages along with the REST API. The training using Twilio's RPG game TwilioQuest also makes it easy to get started. The designer feature makes it easy to design templates without using a third-party solution.

What do you dislike about Twilio SendGrid Email API?

Integrating new senders is not that intuitive on the UI and makes it confusing. Verifying new senders is also not a seamless process as it does not notify if the verification email went through. Sometimes the template designed using the editor does not reflect the email received.

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

We used Twilio SendGrid Email API to send mass emails for our internal and business objectives. We have used Sendgrid using it's API and with other services like Courier, and our implementation has been easy with both the approaches. The high delivery rate along with the statistics from Sendgrid made ensure we had no concerns regarding email delivery.

"A solid API with simple integration into a multitude of different services at an affordable price."
What do you like best about Twilio SendGrid Email API?

The API is easy to integrate with just about any service out there. The documentation is solid and covers multiple use-cases/languages, and the webhooks are reliable and easy to understand. Additionally, the pricing is very reasonable, especially compared to other Email API solutions.

What do you dislike about Twilio SendGrid Email API?

The email design tool is not at polished as competing solutions aimed purely at marketing-based emails (Mailchimp, for example). There are a decent amount of bugs, and it's relatively frustrating to use. Still, we primarily use SendGrid for the API, not the email-design tools, so this is not a dealbreaker for us, and the prices are much more modest than competing marketing solutions.

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

We use the SendGrid Email API to automate internal email delivery from our web and mobile app. We also occasionally use the free marketing and design tools included in SendGrid.

"Email Deliverability and Domain `monitoring"
What do you like best about Twilio SendGrid Email API?

I love SendGrid because it’s so easy to use. I can integrate it with my applications, create templates for mailing campaigns, and send my emails with confidence. The platform is reliable and straightforward to use, and I recommend it to anyone looking for an easy way to send their emails.

What do you dislike about Twilio SendGrid Email API?

Installation of the software was more complex than we expected — especially when it came to getting the system up and running. We contacted the support team several times for help, but only after a few days were we able to get the program running with all stacks we wanted.

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

I use Twilio SendGrid Email API to send emails on behalf of my client. This enables me to send up to thousands of emails daily from the entire bunch of domains and users from their own IPs. The performance of the Sendgrid servers has been very good, and I have not encountered any issues in performing this task.

"Great application for sending mails"
What do you like best about Twilio SendGrid Email API?

The best I like about SendGrid is that I can integrate SendGrid with my applications and create my templates for sending mails. It is very reliable and straightforward to use.

What do you dislike about Twilio SendGrid Email API?

Sendgrid is easy to use, but we have to provide authentication for any emails when sending emails from that email. Also, It is not entirely free, and you can send only a limited number of emails.

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

Because of SendGrid, It is straightforward to send emails from my application itself. It makes the functionality of the application much better, and it seems much more reliable. I can also use it as an email authentication while logging into my application which is very helpful.

"Simple and Reliable Email Client"
What do you like best about Twilio SendGrid Email API?

Great documentation for the API lends to a productive developer experience.

What do you dislike about Twilio SendGrid Email API?

After Sendgrid's acquisition by Twillio, there were many changes to the product (as expected), which unfortunately meant pricing tiers also shifted so features such as the audit history became limited unless you paid more. The API endpoint itself however is versioned so we don't have to worry about breaking changes to our product.

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

Adding email functionality within a cloud-based application. The API offers options for simply sending data to be merged with rich HTML templates, or if you prefer to generate the HTML on your own, you can do that as well.

"SendGrid: Long Overdue Solution for Us"
What do you like best about Twilio SendGrid Email API?

There are a number of strong features in SendGrid. The top two we probably benefit from the most are the API and the reporting. The API makes it simple for our SaaS platform to send e-mails - both from our system to clients, and from our system on behalf of clients (e.g. marketing e-mails). And the API is simple to use and can be integrated in a matter of hours.

What do you dislike about Twilio SendGrid Email API?

The last I reviewed their features, the tools they provide to manage sub-users could be more well developed. We create sub-users to represent each of our clients so that we can track their activity separately. Note: the sub-user feature may be more developed now.

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

There are a number of ways to send e-mail messages programatically. But SendGrid gives our messaging efforts and sound structure. But probably the greatest benefit is the reporting. Tracking things like e-mail opens and bounces takes a lot of development time. SendGrid takes care of these issues for you - allowing you to focus on your core business objectives.

"Easy to Implement"
What do you like best about Twilio SendGrid Email API?

It's very easy to implement SendGrid. I can send emails in just a few minutes. There's multiple ways to implement it into our Laravel applications (SMTP or the API). We integrated with SMTP - the documentation on setting it up was very straightforward. Took less than 30 minutes.

What do you dislike about Twilio SendGrid Email API?

It's difficult to deal with reporting. The reporting tools have change drastically in the past year and a half. I do like the changes you have made, but the amount of data is reduced to just 3 days and it takes longer to pull the data I need. Biggest complaint: Data is only stored for 3 days. I know it costs a lot of money to keep large amounts of data for clients, but I would like to search at least 1-2 weeks of data for a product I pay monthly. Even if it's just basic data (like sends, opens and clicks). I don't necessarily need all of the other data.

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

We needed to send transactional emails (password reset, purchase receipts and event reminders). We are able to send these email effortlessly.

"I would recommend to use Sendgrid"
What do you like best about Twilio SendGrid Email API?

We are b2b platform for igaming and support our customers also by sending CRM email messages to end users. Sendgrid fits the best for this purpose because of possibility to white label senders

What do you dislike about Twilio SendGrid Email API?

Really annoying the stats report. I can't see it in one display by horizontal and need to scroll it all the time and I have no option to customize it somehow. Also, mailbox providers deliverability report is not useful, would be much better to see top10 mailboxes at the report.

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

Very good deliverability even for our industry. Fast and problem solving support White label option

"Solid, reliable and easy to setup system"
What do you like best about Twilio SendGrid Email API?

The user interface is really nice and for marketing, the drag an drop features whilst allowing for code editing in the section is fantastic! This is the first time I have seen in done like this.

What do you dislike about Twilio SendGrid Email API?

Some of the pay walls are a pain, e.g. 3 day transaction history. You need at least 14 days and I am not happy that there are not more bulk email options only 40k and 100k.

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

For us we started using sendgrid just for API sends, but after realising the ease of use for marketing, we migrated from another provider to sendgrid, now all of our emails come from a single source and we like that. It is more time efficient and saves costs.

it is not very accurate for some recipient data, I think that is the only complaint i have about sendgrid but I believe the technical difficulties exist for all vendors.
