An AI email assistant is, in a nutshell, software that helps manage your inbox. It uses Artificial Intelligence to automatically sort, filter, and respond to emails for you. 

AI email assistants use machine learning algorithms trained on huge datasets of emails. They learn to detect patterns that help determine the importance and purpose of incoming messages.

What can you use an AI email assistant for?

Like everything in life, AI email assistants have strengths and limitations. 

First, let’s take a look at what they can do:

• Generating great emails: AI email assistants can create emails from scratch. You provide some basic instructions or context, and the AI will generate a draft for you to review and edit.
• Email suggestions: AI assistants can work within your email client, offering inline suggestions and autocomplete options to speed up your composing process.
• Filtering and prioritizing: AI assistants can learn your preferences and automatically categorize emails as important, urgent, or low priority, saving you time on manual sorting.
• Summarizing long emails: If you're facing a wall of text, an AI assistant can condense the email down to its essential points.
• Translation: Some assistants can translate emails on the fly, breaking down language barriers in communication.
• Reminders: AI assistants can pick up on dates and deadlines mentioned in emails and automatically set reminders for you.
• Data extraction: They can pull out key information (contact details, invoice numbers, etc.) and add those directly to your CRM or management tools.
• Scheduling: If an email discusses scheduling a meeting, an AI assistant can offer to look at your calendar and suggest open slots, times, etc. 

An awesome feature is that, with regular use, an AI assistant adapts to your unique communication style and the types of emails you receive. 

It essentially gets smarter over time, allowing it to handle more of the busy work in your inbox so you can focus on higher-level tasks. (Or playing Solitaire, whatever floats your boat.)

Limitations of AI email assistants

Sounds like all sunshine and rainbows, right? Not quite. 

Here are some limitations of these AI email assistants:

• No complex problem–solving: AI email assistants can’t perform the kind of complex, creative problem–solving that humans do. They can’t brainstorm solutions to thorny issues, provide strategic advice, or think outside the box. 
• Misinterpreting emotional cues: Incorrectly judging the sentiment of an angry customer email could lead to an unsuitable, automated reply, worsening the situation.
• A lack of general strategic understanding: AI cannot replace the nuanced thinking required to decide whether to offer a discount or a free upgrade to resolve a customer issue.
• Not good at tense situations: Drafting an appropriate public response during a company scandal requires sensitivity and understanding that AI just doesn’t have yet. 
• A tendency to hallucinate: An AI assistant suggesting incorrect historical dates in a client presentation could have embarrassing consequences. This is what’s called a hallucination.
