Question: I'm looking for an email client that can manage multiple accounts from different providers in one place.

If you want an email client that can span multiple accounts from different email services in one package, BlueMail is a good option. It supports IMAP, Exchange and POP3 connections so you can have an unlimited number of email accounts in one inbox. With instant push notifications, unified folders and calendar integration, BlueMail helps you keep your email life organized. And with a Generative Email AI (GemAI) powered by ChatGPT, you can summarize and draft emails to get more out of your email. BlueMail is available on Windows, Mac, Linux, Android and iOS. A free, ad-free basic package is available, but premium plans are available.

Another contender is Spark, which uses AI and other technology to help you focus, organize and automate your email. Spark supports a range of email services, including IMAP, iCloud, Exchange, Outlook and Yahoo. It's got smart inbox and home screen features to help you separate the important emails, automated newsletter and notification inboxes to keep them out of the way, and team collaboration tools. Spark's AI-powered email writing assistant offers instant insights, natural language search and email templates to help you draft and manage your email.

If you want an AI-powered email management system, SaneBox is an option. It works with Gmail, Microsoft 365 and Apple iCloud, using machine learning algorithms to sort incoming emails into folders you can use to prioritize your messages. SaneBox has other features like BlackHole to block unwanted senders, Snooze to delay emails, Daily Digest to summarize non-priority emails, and Reminders for unresponded emails. It's got security credentials, too, with annual Google Restricted Scopes verification and continuous testing to ensure your data isn't compromised.

Shortwave is another AI-powered tool to help you get a better handle on your inbox. It offers AI-generated full emails, smart search, instant email summaries, customizable tabs and email grouping. Shortwave supports multiple search options and lets you schedule send and read status tracking. It offers tiered pricing options, including a free package, so it can be a good option for people with multiple email accounts from different providers.
