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…

Dynamic templates have streamlined student and parent email campaigns and build consistent engagement
The activity log is a little slower at times, but that is probably just nitpicking an issue. Overall, in general, there are not really very difficult pain points. There are certain issues sometimes when we are trying to handle a very big campaign; we might end up having a little bit less reputation in terms of bounces or spam reports that get detected when we send out the emails. Apart from that, there is not anything that would become a significant pain point. If you don't really have an advanced subscription for SendGrid, it might take a while for you to reach the customer support.

Quotes from Members

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

Pros

"Every email I send, gets people to click on something or contact me, and it works."
"The fact that we have been a customer for so long indicates how vital this solution is for our organisation."
"It is fun to design your newsletter based on the content you would like to deliver."
"Customer Service: Outstanding, with email, chat and call capabilities even on weekends."
"The ability to email clients using templates setup in the system."
"Just like the name states, it has allowed me to stay in "constant contact" with my subscribers."
"Every time that we send one out, we will get some kind of response."
"Email marketing is the most valuable aspect."
"Easy API documentation is the most valuable feature of SendGrid, including its deliverability rate."
"SendGrid provides the best analytics a competent postmaster needs."
"SendGrid has positively impacted my organization by being a trusted partner for sending emails."
"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."
"They enable us to automate all the communication with our clients around commercial campaigns, marketing activities, and also during transactional tasks, basically, any transaction that happens on the account."
"Overall, my experience with SendGrid is quite good; I have used it in a couple of my projects and everything is smooth, from integration to sending emails; the only aspect I have mentioned several times during this interaction is the pricing."
"The solution scales well."
"Overall, it provides a good return on investment through reliability, time savings, and improved communication."
 

Cons

"Could use better search and certain editing traits."
"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."
"There are certain hiccups in the program that can be improved to make it more user friendly."
"When I started using Constant Contact creating email was very flaky, in terms of crashes and usability (perhaps compared to Weebly etc.). It has improved, however, still needs improvement and email creation still seems clunky and limited compared to other online solutions or website building tools."
"All Constant Contact wants to do is keep you on a monthly subscription, so if you only want to send out emails on a quarterly basis you must either pay every month you do not use the product, or you must cancel your subscription and then re-open an account every quarter."
"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."
"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."
"The biggest problem that we have faced is with the authentication during login."
"I forgot my password, and when I tried to log in, it indicated that a reset link was sent to my email, but I did not receive it."
"SendGrid is already nice, but it could be improved by providing the company ID when sending the email."
"I would prefer an easy plugin for Linux mail installation."
"SendGrid is a great solution. I don't have any areas of improvement."
"Customer Service: 4/5. Technical Support: 3/5."
"Pricing can be improved for SendGrid, as this is the only area I have seen that needs enhancement."
 

Pricing and Cost Advice

"The cost is fair, and you end up making enough in sales to pay for it."
"The solution is relatively inexpensive."
"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 basic plan starts at €90 per month."
"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."
"We are using the Advanced plan,10K. That is about $100 per month but sometimes we do go over the limit of the plan."
"Its cost can vary. It can go as low as $10 or $15 to $1,000 depending on how much you use it."
