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…

Good for digital marketing purposes, such as creating and managing email campaigns
Mailchimp could be more user-friendly for setting up WordPress websites. Some of the complex settings can be time-consuming to configure. So, setting up Mailchimp for WordPress websites can be time-consuming for an average user but not necessarily difficult. It's time-consuming, especially when adding custom code to email campaigns. It requires some experience and knowledge to do it effectively.

Automation Engineer at a educational organization with 11-50 employees
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

"The ability to email clients using templates setup in the system."
"Customer Service: Very good but I would have liked to have 24 hours accessibility."
"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."
"It is fun to design your newsletter based on the content you would like to deliver."
"The fact that we have been a customer for so long indicates how vital this solution is for our organisation."
"Just like the name states, it has allowed me to stay in "constant contact" with my subscribers."
"Email marketing is the most valuable aspect."
"We managed to easily build and send modern, nice looking, relevant newsletters to hundreds of followers, analyze our projects and think of new and better ways to do it, because of the diversity that comes with it."
"I use Mailchimp for digital marketing purposes, such as creating and managing email campaigns, collecting data, and integrating with WordPress websites."
"MailChimp is solid and easy to use for clients, but has all the power we need to build great campaigns, A/B test them, get them delivered, tracked, and report."
"We have been happily using MailChimp for all our email marketing needs."
"This is the cheapest, simplest and easiest white-listed provider to use."
"It’s very easy, and you can start using it without being an expert in e-marketing."
"MailChimp enables us to manage how the content crosses over and monitors each series or campaign while providing in-depth analytics for each vertical market."
"We used to use VerticalResponse but made the switch because we found MailChimp to be easier and faster to work with."
"SendGrid offers features that stand out for me, including that it is very easy to use, especially for a developer."
"SendGrid has positively impacted my organization by being a trusted partner for sending emails."
"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."
"With SendGrid, we have found a perfect solution to that scenario, and we don't have to involve infrastructure team anymore."
"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."
"It is a stable and scalable solution."
"Easy API documentation is the most valuable feature of SendGrid, including its deliverability rate."
"The solution scales well."
 

Cons

"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."
"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."
"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."
"Its admin interface, particularly for setting up a new campaign, is not the most intuitive."
"It would be great to be able to create broader segments for campaigns."
"They have poor inbox visibility, and many of the emails went to the spam folder."
"It needs more formatting flexibility, such as the ability to wrap text around photos."
"A standalone system for private servers would be ideal."
"The solution should improve its reporting feature. There should be more transparency around API development. At the moment, the clients are pushing custom API into the mail, so we don't have too much visibility regarding what endpoints they're pushing the data into."
"MailChimp’s reports on audience engagement are not the most robust."
"Pretty much everything, and the RSS campaign is the only reason we stick with MailChimp."
"Maybe they could have a mobile application to give to admins, so they could see some insights related to the data."
"They are backlogged on feature requests, which is a bit of a shame really."
"The documentation is not fine, so I believe the documentation needs 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."
"If you don't really have an advanced subscription for SendGrid, it might take a while for you to reach the customer support."
"SendGrid could improve pricing flexibility and offer more detailed analytics without extra cost."
"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."
"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."
"MailChimp is affordable."
"I primarily use the free version, but sometimes, for specific client needs, we may have to purchase different versions or packages."
"Its cost can vary. It can go as low as $10 or $15 to $1,000 depending on how much you use 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 solution is relatively inexpensive."
"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 basic plan starts at €90 per month."
"We are using the Advanced plan,10K. That is about $100 per month but sometimes we do go over the limit of the plan."
