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.
