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.
Rastu Singh - PeerSpot reviewer
Clean and simple to use with good integration capabilities
There are lots of things that are quite good with SendGrid as compared to other platforms. For example, it is very easy to set up, and it is very clean and simple to use. The email integration is fairly easy, and I can say it is reliable. It also allows you to implement services from other platforms as well. So you can have multiple things in a single place. We're using the API. They provide certain add-ons, like Azure add-ons. You can connect with Azure as well. They have decent support in terms of any issues. They have a nice dashboard as well. It gives almost all information in a single place, and it is scalable.

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."
"MailChimp has many capabilities."
"I use Mailchimp for digital marketing purposes, such as creating and managing email campaigns, collecting data, and integrating with WordPress websites."
"MailChimp's most important functionality is its automation feature."
"It allows for dragging and dropping, which is much faster than writing HTML and CSS."
"The email scheduling has been quite useful."
"Running email campaigns is easy and straightforward."
"Easy API documentation is the most valuable feature of SendGrid, including its deliverability rate."
"They have pretty good support in terms of any issues."
"It is easy to set up."
"It is a stable and scalable solution."
"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."
"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."
"The solution scales well."
"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."
"The solution could be easier to use."
"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."
"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."
"A standalone system for private servers would be ideal."
"It needs more formatting flexibility, such as the ability to wrap text around photos."
"I don't have any issues with the service."
"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."
"Maybe they could have a mobile application to give to admins, so they could see some insights related to the data."
"SendGrid is a great solution. I don't have any areas of improvement."
"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."
"The contact limit alerts need to be improved."
"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."
"They should make the solution more user-friendly."
"The reporting part needs improvement."
 

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."
"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."
"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."
