Spark does every inbox. Dodosend does Gmail, from the keyboard.

Spark is a friendly email app for any provider, free to start and on every device. Dodosend is narrower on purpose: Gmail only, desktop only, built to be run from the keyboard. Here’s how they compare.

Which one is for you

Pick Dodosend if…

You live in Gmail
Dodosend is built on Gmail itself: your labels, Gmail’s search operators like from: and has:attachment, and every folder in one search.
You’d rather not touch the mouse
Every action in Dodosend has a key, ! shows the ones for the screen you’re on, and ⌘K reaches everything else.
You’re on Linux
Dodosend has a Linux desktop build, as an AppImage, a .deb and an .rpm. Spark’s apps are for Mac, Windows and phones.
Your calendar is part of triage
The week view is G then C away, and ⌘⇧A pastes your free slots into a draft as a sentence.

Pick Spark if…

You have more than Gmail
Spark connects Outlook, Exchange, Yahoo, iCloud and other IMAP accounts. Dodosend is Gmail and Google Workspace only, for now.
You want several accounts for free
Spark’s free plan takes unlimited accounts. Dodosend’s covers one mailbox; more need the Multi-mailbox plan.
You read mail on your phone
Spark has iPhone and Android apps. Dodosend is a desktop app; on your phone you’d still use Gmail.
You want a settled app
Dodosend is still in beta: it changes often, and you may hit a rough edge. If you’d rather not, Spark is the steadier choice.

Switching from Spark

Your mail stays in Gmail, so there’s nothing to move: sign in to Dodosend with Google and your threads and labels are there. Keep Spark on your phone if you like; both work on the same account.

Questions

Is there Spark for Linux?

No. Spark’s apps are for Mac, Windows, iPhone and Android. Dodosend runs on Linux as an AppImage, a .deb or an .rpm, for x86_64.

Does Dodosend support Outlook or iCloud?

Not yet. Dodosend supports Gmail and Google Workspace accounts. More providers are on the roadmap.

Is Dodosend free?

Yes, for one Gmail mailbox, with every feature: the command palette, reminders, scheduled send, the calendar, and a few Ask AI questions a day. The Multi-mailbox plan, billed monthly or yearly, connects more mailboxes and gives more AI.
