The API itself works fine. The UI is relatively easy to navigate. It does everything you'd need an email API to do. As long as you don't mind constantly being suspended for false flags and getting support at least 3 business days later every time.

There is zero support when the system automatically flags you for "unusual" activity. We have a 99% reputation according to SendGrid with 0 spam reports and 0 unsubscribes. Our app traffic tends to surge on one day each week according which causes our emails to surge on that day as well. We have been with SendGrid for about 3 months and have now been suspended 4 times and each time they say it was a false suspension. But there is no response for DAYS each time.

Outsourcing our SMTP infrastructure. Giving insights into our email traffic to our support staff.

In a few steps i created an account and get the API key. It works great also in the free version.

At the moment there is nothing I dislike.

I needed an integration to send email from a Bot in BotPress.

ease of integration and user friendly gui.

all is good so far . nothing wrong. i like the product

with Twilio send grid , i am able to send transactional emails from multiple applications

Excellent reporting and the API Key was straightforward to integrate with the 3rd party software I am using

Nothing negative to report in the short time I have been using SendGrid

It has assisted us in having an improvement on Open rates and reply rates.

We use the SendGrid API for integration into at least 20 Wordpress websites. As well as custom deployments. The ease-of-use and documentation are matched by none.

Not many things, multiple user support would be a great addition for agencies.

Ability to send transactional email in a breeze. Great reporting helps us determine successful integrations AND ensures customers are getting the important emails they ask for.

Ability to send bulk number of sms using SMTP.

Limitation of recipients and the max limit of attachment

Emails are getting delivered on time. Level of spam is very low.

Trace of each email sent and communicated.

Limited information shared to understanding the communication sent out.

Able to trace the date when the communication was sent out and the time stamp of when it was retrieved by the recipient.

SendGrid makes my life so much easier! I use it nearly daily in my capacity as a technical support specialist, and email issues are not uncommon. SendGrid not only makes the whole emailing setup and process seamless and easily integrates with all of our software, but also provides huge transparency and reporting into all of its functions. It's Integration guide is also quite comprehensive and really helps with the initial setup.

I would definitely expand the "knowledge base" and the integration guide to be more detailed and answer niche questions

Personally, I don't use much of its setup functions, but extensively make use of its reporting functions - the activity section. It provides exceptional visibility into email deliverability and any issues/errors making it really easy to troubleshoot

Easy interface, customer support is top-notch.

Not possible to speak to someone with paid account.

Mass emails
