Reviews from experts

SendGrid

SendGrid's email editor allows you to customize existing templates, build a new email newsletter with the drag-and-drop functionality, or code an email from scratch. You can customize the design of the email by changing attributes such as background color, text, and font, as well as add new content blocks, including buttons, images, texts, and snippets of code.
One of the most useful aspects of the email editor is the ability to add tags in the message, which allow you to add custom fields. This includes adding the recipient's name and location, date of last open, or any other information you collect on your subscribers, which enables a high level of personalization.

Sendgrid is a powerful email marketing tool that offers superior services to its customers. Sendgrid is a must-have tool for start-ups, eCommerce businesses, freelancers and corporates. One thing that separates Sendgrid from other email marketing tools is their scalability once our list grows. The free version of Sendgrid allows you to send 100 emails every day.
What I like most about Sendgrid is that most of the tools out there offer easy integration with Sendgrid. Some apps can even directly integrate with SendGrid without using automation software like Zapier.

Constant Contact

Pros: The email templates are easy to use, and I've been able to train multiple users in our organization to use it, who don't have a background with tools like this. As an email tool, I'm very happy.
Cons: As a social tool, I'm disappointed. Right now you can't post to Twitter (X) at all. You can't upload videos to share as Reels, and if you want to edit copy for each social media platform you have to make separate posts.

Pros: Constant Contact is very intuitive and user-friendly. People with no email experience can easily jump in and create nice-looking emails. <...>
Cons: Since I started using Constant Contact in 2019, the platform is virtually the same. <...> Unfortunately, we have used Constant Contact to its capacity. Our emails cannot improve or change with the features that are currently available. It would be nice to see more customization in emails and better analytics reporting!
