General

Pricing

MailMaestro is competitively priced at $15 per month, offering affordability. In contrast, Copilot is priced at $30 per month, presenting a higher investment.

Technical and commercial requirements

MailMaestro offers extensive compatibility, supporting Outlook on various platforms including Windows, Mac, Web, and soon on Gmail and mobile, requiring just an internet connection. It's accessible for all Professional and Enterprise licenses.

Copilot, conversely, is restricted to newer versions of Outlook and necessitates Microsoft Enterprise licenses.

Large Language Models (LLMs) utilized

MailMaestro and Copilot both leverage OpenAI's GPT 4o for their sophisticated and contextually aware text generation.

Unlike Copilot, MailMaestro is LLM agnostic, integrating models beyond OpenAI’s offerings like Google's PaLM, Claude 3.5, Jurassic, among others, and even allows for custom model integration. This LLM agnosticism affords the flexibility to connect with the most efficient LLMs for specific use cases or languages.

Custom integration

MailMaestro shines in its ability to meet customer-specific needs, offering custom integration APIs to connect with clients' databases, knowledge libraries, and more. Copilot's customization aligns more with general user preferences and organizational data access, integrating with Microsoft 365's data sources to tailor user experiences.

Features & Functionalities

Compose emails

MailMaestro and Copilot both excel in crafting emails under user guidance. They support multilingual email creation, but MailMaestro's language support is notably more robust, with 16 supported languages, including English, German, Spanish, French or Dutch. Unique to MailMaestro is the ability to save prompts, enabling users to efficiently reuse them in the future.

Copilot, on the other hand, distinguishes itself by customizing its email drafting process to suit user preferences, tapping into Microsoft 365's data sources to ensure each email composition feels personal and relevant to the user's needs.

Improve existing emails

MailMaestro sets itself apart with a feature designed to enhance already written emails. This tool allows users to either completely overhaul an email or focus on refining specific sections. It supports direct user interaction, enabling precise and targeted improvements to existing email drafts, a functionality that adds significant value to email composition and revision processes.

Coaching

Copilot boasts a distinctive feature where it evaluates emails based on four key aspects: overall quality, tone, clarity, and sentiment, subsequently providing suggestions for enhancement. Conversely, MailMaestro stands out with its significant "Improve existing draft" feature, which allows for detailed refinement of email drafts as outlined earlier.

Summarization capabilities

AI Email Summaries

Both tools proficiently summarize email threads. However, MailMaestro takes an extra step by providing these summaries in multiple languages. Also allows to get more details and highlight action points relevant to the user.

Attachment summaries

Copilot focuses on summarizing Word documents and this functionality is not currently available on Outlook directly. In contrast, MailMaestro extends its capabilities to include both Word and PDF documents, and offers this feature in various languages.

Inbox summaries

Copilot can summarize the inbox, currently available in MS365 chat. As of now, MailMaestro has not ventured into providing inbox summary functionalities.

Prompt history, Email templates, and Text shortcuts

MailMaestro archives user prompts and provides ready-to-use templates for common emails. It also offers text shortcuts for frequently used email snippets, enhancing productivity.

Calendar scheduling

MailMaestro excels in AI calendar scheduling, detecting meeting invites and suggesting responses without user input. Copilot currently has no calendar integrations.

Mobile accessibility

Copilot emphasizes mobile functionality through the Outlook Mobile app, offering versatile email generation and customization options. MailMaestro will extend its services to both Android and iOS devices soon.

Conclusion

In conclusion, MailMaestro and Copilot for Outlook each present a unique suite of features that significantly enhance email management. MailMaestro stands out with its versatile LLMs, broad platform compatibility, and tailored client solutions, making it an optimal choice for businesses in search of customized email assistance.
