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

"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."
"The ability to email clients using templates setup in the system."
"Every email I send, gets people to click on something or contact me, and it works."
"Email marketing is the most valuable aspect."
"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."
"Customer Service: Very good but I would have liked to have 24 hours accessibility."
"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."
"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."
"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."
"The best features SendGrid offers is the template customization, which really helps in creating templates according to client demand and their UI/UX experience."
"White-listed mail which avoids spam on mail services like Gmail and Yahoo."
"SendGrid is a very good, reliable system for handling multiple or high-volume emails."
"The most valuable feature is the conditions in automation."
 

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."
"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."
"Could use better search and certain editing traits."
"There are certain hiccups in the program that can be improved to make it more user friendly."
"The documentation is not fine, so I believe the documentation needs to be improved."
"SendGrid could improve pricing flexibility and offer more detailed analytics without extra cost."
"The reporting part needs 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."
"The contact limit alerts need to be improved."
"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 can be improved by making it more versatile and facilitating easier connections with third parties."
"SendGrid is already nice, but it could be improved by providing the company ID when sending the email."
 

Pricing and Cost Advice

"The cost is fair, and you end up making enough in sales to pay for it."
"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."
"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."
"We are using the Advanced plan,10K. That is about $100 per month but sometimes we do go over the limit of the plan."
