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

"It is fun to design your newsletter based on the content you would like to deliver."
"Email marketing is the most valuable aspect."
"The fact that we have been a customer for so long indicates how vital this solution is for our organisation."
"Every email I send, gets people to click on something or contact me, and it works."
"Every time that we send one out, we will get some kind of response."
"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."
"The API configuration is much cleaner in SendGrid."
"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."
"Since switching to SendGrid, I have seen that time is saved, and the trust of the portals like Gmail and Outlook ensures the emails are received quickly with minimum failure, which increases the business."
"Overall, it provides a good return on investment through reliability, time savings, and improved communication."
"SendGrid has positively impacted my organization by being a trusted partner for sending emails."
"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."
"SendGrid is a very good, reliable system for handling multiple or high-volume emails."
"They have pretty good support in terms of any issues."
 

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."
"There are certain hiccups in the program that can be improved to make it more user friendly."
"Could use better search and certain editing traits."
"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."
"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."
"So, don't think that you could do anything with SendGrid on email matters."
"I would prefer an easy plugin for Linux mail installation."
"They are backlogged on feature requests, which is a bit of a shame really."
"They should make the solution more user-friendly."
"The biggest problem that we have faced is with the authentication during login."
"They are very bad at supporting clients."
"The reporting part needs improvement."
"The contact limit alerts need to be improved."
 

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."
"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."
"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."
"The basic plan starts at €90 per month."
