SevenMail and Spark

Where your mail goes

A new mail leaves Google and ends up on your Mac. What happens on the way differs.

SevenMail

Between Google and your Mac. Nothing of ours in between.

Each line is the route as the vendor’s own pages and policy describe it. Where a page does not say, the box says so. This is a description, not a security rating.

SevenMail and Spark

Where SevenMail is different

Boards and tasks

Spark lists a Smart Inbox with pins and priorities, and no boards. SevenMail’s board lets you drag mail between columns, and suggests tasks from requests and deadlines.

An AI on your Mac

Spark’s policy says its AI works on the device and/or with providers it names (Azure OpenAI, OpenAI, Anthropic, Google). SevenMail’s runs on your Mac with Apple Intelligence.

EUR 79.99 a year for everything, against USD 99 for Plus and USD 199 for Pro.

SevenMail and Spark

Switching

Your mail, labels and stars live in Gmail. Switching is signing in with Google.

  1. 1Sign in with Google

    In SevenMail, choose your Google account. That is the whole setup.

  2. 2Your mail is already there

    Labels, stars and the archive live in Gmail, so they appear as you left them.

  3. 3Copy what stays behind

    Settings inside the old app do not move. Copy what you want to keep first.

Good to know

Spark and SevenMail both work on your Gmail, so your labels, stars and archive are already in Google. Sign in with Google in SevenMail. What lives inside Spark, such as pins, set-aside mail, team comments and templates, stays in Spark, so copy what you want to keep first.

Questions

Is SevenMail released?+

Not yet. A closed beta comes first; the waitlist on the home page is the way in. The table marks what is in the beta and what is planned, and we change this page when that changes.

Does SevenMail work with my other mail accounts?+

Not yet. SevenMail works with Gmail and Google Workspace accounts only. Spark supports several kinds of accounts.

What happens to my mail in each app?+

In SevenMail, your mail goes between your Mac and Google, and a copy stays on your Mac. Spark’s notice says email data is mainly processed on your device, may be processed in Spark systems when a feature needs it, and is not stored there in transit. Read both policies for the details.

Can SevenMail replace Spark for a team?+

No. SevenMail is for one person: there are no shared inboxes, shared drafts or assignments.

Does SevenMail have a free plan?+

No. There is a 14-day trial, then EUR 8.99 a month or EUR 79.99 a year. Spark has a free plan.
