Owner/Founder at a tech services company
It enables me to create and manage an auto-responder series along with list growth management tools.
The goal is to continue to engage with my list. Keeping in touch with new and potential customers helps stay "on top of mind" when needing services.  Just like the name states, it has allowed me to stay in "constant contact" with my subscribers. The most valuable features are creating and…

Saves server load by sending bulk email notifications efficiently
The best feature SendGrid offers is the ability to send multiple emails at the same time. The ability to send multiple emails at the same time helps my workflow and organization because I do not have to run a loop every time. Once I set all the emails in a comma separator, I can send them to multiple users without creating too much load on my server. SendGrid has positively impacted my organization by solving the notification problem. By using SendGrid, I can easily send notifications to users, and it is simple to use in my Node.js project. SendGrid has helped with notifications because when I send an email, the user knows who is sending it and they can revert back to our CRM team. That is positive for our business and organization.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It is fun to design your newsletter based on the content you would like to deliver."
"The most valuable feature is the conditions in automation."
"They have pretty good support in terms of any issues."
"Easy API documentation is the most valuable feature of SendGrid, including its deliverability rate."
"It is easy to set up."
"The API side of things is valuable. It is flexible enough to handle pretty much anything that needs to be done in an automated manner."
"The solution scales well."
"My integration team likes that it's very easy to integrate and very easy to automate based on activities that happen on our core banking application."
"It is a stable and scalable solution."
 

Cons

"Sometimes, you will be typing in a text box and hit the backspace, but the website will think you meant to go back a page. Basically, you end up losing work when this happens and it is hard to predict."
"The biggest problem that we have faced is with the authentication during login. For certain people, SendGrid requires MFA, which is good as a security feature, but it doesn't always work in all geographies. We've got people and users who are based in Nigeria, and some of those people had real trouble logging into SendGrid because the MFA wouldn't send codes to people on their numbers. The security mechanism that they use for login doesn't work in all geographies."
"Maybe they could have a mobile application to give to admins, so they could see some insights related to the data."
"SendGrid has room for improvement in the UI/UX or dashboard usability for users. Another area for improvement in the tool is its conditional logic facilities. The response time of SendGrid technical support needs improvement."
"They should make the solution more user-friendly."
"The reporting part needs improvement."
"The contact limit alerts need to be improved."
"SendGrid is a great solution. I don't have any areas of improvement."
"A long time ago, I may have had an issue, and I had to wait for support, which wasn't that helpful. However, that was a very long time ago. Overall, I've had a good experience."
 

Pricing and Cost Advice

"The cost is fair, and you end up making enough in sales to pay for it."
"Its cost can vary. It can go as low as $10 or $15 to $1,000 depending on how much you use it."
"We are using the Advanced plan,10K. That is about $100 per month but sometimes we do go over the limit of the plan."
"My company pays for SendGrid monthly, and though I cannot share the amount, my feedback is that the vendor should accept other modes of payment apart from a credit card."
"I use the essential plan which is $20 a month. After that, we use the pro which is $90 a month, and had all our costs bundled in."
"The solution is relatively inexpensive."
"The basic plan starts at €90 per month."
