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

"Customer Service: Very good but I would have liked to have 24 hours accessibility."
"Customer Service: Outstanding, with email, chat and call capabilities even on weekends."
"Email marketing is the most valuable aspect."
"Every email I send, gets people to click on something or contact me, and it works."
"Just like the name states, it has allowed me to stay in "constant contact" with my subscribers."
"The ability to email clients using templates setup in the system."
"Every time that we send one out, we will get some kind of response."
"The fact that we have been a customer for so long indicates how vital this solution is for our organisation."
"SendGrid is a very good, reliable system for handling multiple or high-volume emails."
"Overall, it provides a good return on investment through reliability, time savings, and improved communication."
"The valuable features include email capabilities, among other offerings."
"The API configuration is much cleaner in SendGrid."
"The most valuable feature is the conditions in automation."
"In my experience, the best features SendGrid offers include the dashboard, which is very nice to review if emails were delivered or if something was wrong."
"SendGrid provides the best analytics a competent postmaster needs."
"SendGrid has positively impacted my organization by solving the notification problem."
 

Cons

"There are certain hiccups in the program that can be improved to make it more user friendly."
"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."
"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."
"Could use better search and certain editing traits."
"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."
"SendGrid is a great solution. I don't have any areas of improvement."
"SendGrid has positively impacted my organization as we moved to it from our own email servers, though it also gives us less control over everything."
"SendGrid is already nice, but it could be improved by providing the company ID when sending the email."
"They are backlogged on feature requests, which is a bit of a shame really."
"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."
"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."
"SendGrid could improve pricing flexibility and offer more detailed analytics without extra cost."
 

Pricing and Cost Advice

"The cost is fair, and you end up making enough in sales to pay for it."
"The basic plan starts at €90 per month."
"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."
"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 solution is relatively inexpensive."
"Its cost can vary. It can go as low as $10 or $15 to $1,000 depending on how much you use it."
