Brian Chesky, Airbnb's cofounder and CEO, says he has largely moved away from email as a communication tool. He said he now favors voice memos, describing them as creating a 'deeper connection' and feeling less like work to respond to than written messages.
Apple's iOS 18.2 update introduced a Categories feature in the Mail app that automatically sorts incoming messages into Primary, Transactions, Updates and Promotions tabs. The feature is enabled by default, but users can turn it off to restore the app's previous single-inbox layout, and can manually reassign emails that land in the wrong category.
A new email service called Clova.Email lets users claim an address prefix of five or more characters, after which only the first sender to email that address is ever accepted again. The app also offers an MCP integration so AI assistants like Claude or Cursor can be granted limited permissions to manage inbox tasks such as generating addresses or retrieving codes and receipts. Sign-in options include Google, passkeys, or username and password, with Google logins sharing only email, name and photo.
Cisco has released a patch for CVE-2026-76519, a path traversal bug in Secure Email Gateway's Advanced Malware Protection feature that lets unauthenticated attackers send a malicious email attachment to gain root-level command execution on unpatched devices. Cisco's security team said it detected active exploitation of the flaw in October 2026 and published indicators of compromise for administrators to check their systems. The vulnerability only affects devices with File Reputation enabled and running Content Scanner Tools versions earlier than 25.3.0.5525.
Apple has rolled out several new perks for iCloud+ subscribers over the past few weeks, including upgraded HomeKit Secure Video with 4K support, AI-generated clip descriptions and searchable footage tied to iOS 27.

X's Grok Bot can now claim a personal inbox ending in @mail.grokbot.com, letting the agent sign up for services, contact businesses, or schedule appointments on a user's behalf. Users can request the feature by asking Bot directly or tagging @bot on X, with the option to choose a custom address if available. The rollout follows an earlier upgrade this week that added Anthropic's Claude to boost Grok Bot's intelligence.
An Entrepreneur contributor describes organizing multiple ChatGPT instances into a coordinated team for solo business owners, assigning each a specialized role such as email strategy, content research and campaign scheduling. The setup includes an always-on AI agent acting as a chief of staff to hand off tasks between the specialized assistants, built using separate ChatGPT projects with tailored instructions and files for each role.
Cybersecurity analysts caution that as businesses grant AI agents authority to interact with payment and vendor systems, attackers can target those agents directly through prompt injection rather than tricking human employees. Verizon's 2026 Data Breach Investigations Report found third parties were involved in 48% of breaches, up 60% year over year, while the FBI's IC3 recorded about $3 billion in BEC losses in 2025.
Penguin Mail is a new open-source email client built in Rust for Linux, supporting Gmail, Outlook, iCloud, Fastmail and generic IMAP/POP3/SMTP accounts with automatic server detection. It unifies multiple accounts into one synced inbox with tray notifications, and bundles calendar, contacts, OpenPGP/S-MIME encryption via GnuPG, and support for provider-side filtering rules like Gmail filters and Sieve.
Google is rolling out its Email Verification origin trial to Chrome on Android, adding a 'Verified Email' option under Settings > Addresses with an auto-confirm toggle. The feature lets Chrome confirm a user's email address directly with a supporting email provider, skipping the usual verification email or one-time code, though both the site and provider must support Google's protocol.
