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.

Saves server load by sending bulk email notifications efficiently
The best feature SendGrid offers is the ability to send multiple emails at the same time. The ability to send multiple emails at the same time helps my workflow and organization because I do not have to run a loop every time. Once I set all the emails in a comma separator, I can send them to multiple users without creating too much load on my server. SendGrid has positively impacted my organization by solving the notification problem. By using SendGrid, I can easily send notifications to users, and it is simple to use in my Node.js project. SendGrid has helped with notifications because when I send an email, the user knows who is sending it and they can revert back to our CRM team. That is positive for our business and organization.

Pros

"It is fun to design your newsletter based on the content you would like to deliver."
"Just like the name states, it has allowed me to stay in "constant contact" with my subscribers."
"Customer Service: Very good but I would have liked to have 24 hours accessibility."
"Email marketing is the most valuable aspect."
"Customer Service: Outstanding, with email, chat and call capabilities even on weekends."
"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."
"The fact that we have been a customer for so long indicates how vital this solution is for our organisation."
"Their technical support is excellent."
"Customer Service: Excellent. Technical Support: Very good."
"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."
"I like the ease of configuration and the templated emails."
"Dragging and dropping is much faster than writing HTML and CSS."
"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."
"MailChimp almost doubled our email marketing delivery and open rates."
"We do more outbound marketing as this method makes it so much easier to do."
"The solution scales well."
"White-listed mail which avoids spam on mail services like Gmail and Yahoo."
"Easy API documentation is the most valuable feature of SendGrid, including its deliverability rate."
"They have pretty good support in terms of any issues."
"The API side of things is valuable. It is flexible enough to handle pretty much anything that needs to be done in an automated manner."
"The most valuable feature is the conditions in automation."
"With SendGrid, we have found a perfect solution to that scenario, and we don't have to involve infrastructure team anymore."
"SendGrid provides the best analytics a competent postmaster needs."
 

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."
"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."
"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."
"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."
"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."
"Automated workflows do not have control for dynamic behavioral targeting in any way."
"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."
"List management could be more scalable."
"The solution could be easier to use."
"Sadly now Mailchimp has started charging for the use of the auto-responder (automation) emails, so it's lost it's edge for the free services."
"The training materials need work."
"Automation workflows have limited trigger options."
"They are backlogged on feature requests, which is a bit of a shame really."
"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."
"I would prefer an easy plugin for Linux mail installation."
"SendGrid could improve pricing flexibility and offer more detailed analytics without extra cost."
"Maybe they could have a mobile application to give to admins, so they could see some insights related to the data."
"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."
 

Pricing and Cost Advice

"The cost is fair, and you end up making enough in sales to pay for it."
"I primarily use the free version, but sometimes, for specific client needs, we may have to purchase different versions or packages."
"MailChimp is affordable."
"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."
"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."
"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."
