What are Internal Email Platforms and Why Are They Necessary?

Internal email platforms are specialized internal communication tools designed to elevate plain text emails. They can provide sophisticated design features, comprehensive analytics,  enhanced security, and other features that help you get more out of email.

Here are just a few benefits of internal email apps in the modern workplace:

Upgrading Basic Outlook and Gmail: The latest internal communications email software integrates with Outlook and Gmail while enhancing their capabilities with stronger security, engaging internal email design features, customizable newsletter templates, and so much more.

Driving employee engagement: While email providers like Outlook and Gmail are focused on distributing information, internal email platforms are designed to build dialogue with employees. They foster employee engagement by offering interactive features like employee pulse surveys, anonymous comments, clickable content, and other interactive capabilities.

Understanding staff with employee feedback: internal email software allows users to try out creative employee newsletter ideas such as collecting employee feedback directly within emails. Gathering consistent employee feedback is easy and quick with the help of embedded employee pulse survey questions.

Optimizing emails with analytics: a key benefit of internal email platforms is that they let you understand your audience better. They do this by going beyond the open rates and clicks to reveal read times, most popular clicks, best email scheduling times, and the most engaged business locations. 

Delivering tailored emails with audience segmentation: Internal email tools with list management capabilities allow you to automatically divide, organize, and update internal email lists for more targeted messaging. 

Can I use Mailchimp or another email marketing software for internal communications? 

Mailchimp and other external email marketing tools were designed for customer engagement. They lack key security features necessary to protect sensitive internal data and the interactive capabilities to engage employees.

Moreover, email marketing tools like Mailchimp treat employees like customers, allowing them to unsubscribe from key company updates and alerts. This is risky business if you’re sending crisis communications or simply trying to build employee engagement.

Unlike internal email software,external email tools lack specialized functionalities that help optimize internal communications. Employee feedback collection and interactive features are limited across external email tools—they’re designed to deliver information—not start a dialogue.

Luckily, there are plenty of Mailchimp alternatives designed specifically for internal communications. Read on as we cover them below.
