SaneBox vs Spark Mail

SaneBox

• People who want to keep their current email app and add smarter filtering
• Inboxes crowded with newsletters and notifications
• Anyone who wants a reminder when a sent email gets no reply

Spark Mail

• People juggling several email accounts across desktop and phone
• Individuals who want a free client with a unified inbox and send later
• Small teams that want to comment on emails and draft replies together

SaneBox

• There is no free plan; a paid subscription is needed once the free trial ends.
• Snack covers 1 email account and 2 features, and Lunch covers 2 accounts and 6 features. Only Dinner includes everything.
• It is not an email client: the iOS and Android apps are companions for digests, snoozing and blocking senders.
• Prices here are the US App Store's in-app prices. SaneBox's own pricing page can show different figures and also sells a two-year term.

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.

SaneBox

SaneLater filtering

Analyzes how you handle email to judge what matters, then moves unimportant messages out of the inbox into a separate SaneLater folder.

SaneBlackHole

Send a sender to the BlackHole and their future messages are kept out of your inbox for good.

Daily Digest

A daily summary of the unimportant, unopened email that was filtered. Digests can also be processed in the iOS and Android companion apps.

Snooze and follow-up reminders

Snooze folders bring a message back to the inbox later, and SaneReminders flags sent emails that have not received a reply.

SaneDoNotDisturb

Holds incoming email during quiet time set aside for focused work and delivers it afterwards.

Works with your current email

Connects to Gmail, Microsoft 365, iCloud, Yahoo, Fastmail, IMAP and Exchange accounts, so its folders show up in whichever email client or device you use.

Spark Mail

Smart Inbox and unified inbox

Brings every connected account into one inbox and separates priority mail from newsletters and notifications. Included in the free plan.

Gatekeeper and Priority

Gatekeeper lets you accept or block new senders before they land in the inbox, and Priority highlights chosen senders. Both are part of Plus and above.

Spark +AI and AI Assistant

+AI drafts, proofreads, summarizes and translates email. The AI Assistant answers questions about your mail, reaching back 1 month on Free, 1 year on Plus and without limit on Pro.

Snooze, Send Later and reminders

Snooze a message, set it aside, schedule a send or get a follow-up reminder. These scheduling tools are in the free plan.

Team collaboration

Share a thread with teammates, discuss it in private comments and write drafts together in real time. Shared inboxes for addresses such as support@ need Pro.

Calendar and AI meeting notes

A built-in calendar can add Zoom, GoTo or Microsoft Teams call links. AI meeting notes are capped at 5 in total on Free and 40 a month on Plus, and unlimited on Pro.
