Spark Mail

• Verify Sender phishing warnings, Validate Contacts and LinkedIn Discovery need Edison Mail+ at $14.99 a month or $99.99 a year.
• Edison's site still mentions a Mac app, but the Mac App Store link from its launch post returned no listing when checked, so Mac is not listed here.
• Assistant features for bills and receipts, entertainment, travel and package alerts are limited to the US, UK, Canada, Australia and India.

Spark Mail

• The vendor lists apps for Mac, Windows, iOS and Android only; there is no web or Linux version.
• Gatekeeper, Priority, Spark +AI and third-party integrations require Plus or higher.
• Shared inboxes, read statuses and the HubSpot integration are limited to Pro and Enterprise.
• The free plan's AI is a limited preview: 5 meeting notes in total and 1 month of email history for the AI Assistant.
