Is email alerting free?

Yes. Email alerts are on every plan including Free, along with the other twelve providers — Slack, Microsoft Teams, Google Chat, Discord, Telegram, Mattermost, ntfy, Feishu/Lark, DingTalk, WeCom, webhooks and Zapier.

What relevance floor should I use for email?

90. Email is for escalations, not for reading, and it is the channel where too much traffic causes the most damage — someone writes a filter rule, the mail keeps arriving, the channel keeps reporting healthy, and nobody sees any of it. A chat channel at least gets muted visibly.

Can I send alerts to several people?

Add a channel per person. An email channel only mails a verified member of your organization, so a shared alias or an outside address will not work. Each channel carries its own relevance floor and its own events, so on-call at 90 and a founder at 95 are two channels rather than one with a list.

Can I get a daily digest instead of one email per mention?

Yes, two ways. The Daily brief is a once-a-day email, on every plan, with the posts worth engaging with today and any keyword spikes — members get it unless they turn it off. And an email alert channel batches bursts: the first mention arrives at once, and the rest of the window (five minutes by default, up to an hour) as one digest email.

How quickly does an email arrive?

The first mention to clear the floor is mailed as soon as it is read; any more within the burst window follow as one digest. The real limit is how often FishOut collects rather than how fast the mail sends: hourly on every plan, and every 15 minutes on Reddit, Hacker News and Bluesky for keywords you mark Fast on a paid plan.

Email is the channel that works when nothing else does: no app to install, no workspace to join, no bot to authorise. It is on every plan, like every other provider, and it is the one where the relevance floor should be highest.

[02] CONNECT IT/ SETUP

Point FishOut at an address

3 steps, a few minutes end to end.

1
Add an address
Under Settings → Notifications, add an email channel and enter the address. It has to be the verified address of a member of your organization — FishOut re-checks that at send time, so alerts never go to an outside address. There is nothing to install on the other end.
destination
```
sam@acmemail.com
```
2
Set the relevance floor high
Higher than any of the chat channels. Email is where the escalations go, not where the reading happens — at 90, only the most relevant posts reach anyone, and a burst arrives as one digest email rather than a stack of them.
3
Pick the event
mention.scored is the one to subscribe to: it fires when the AI read is done, so it is the first event that carries a relevance a floor can filter on. reply.drafted is worth adding if you want to know when a reply draft is written.

Then set the floor

Email is the channel where a low relevance floor does the most damage, because an inbox has no scrollback that anyone forgives. A chat channel that fires too often gets muted; an email address that fires too often gets a filter rule, and a filter rule is invisible — the alerts keep sending, the delivery count keeps rising, and nobody reads any of it. Set it at 90 and let the inbox carry the rest.

What Email receives, field by field

Built from the event’s envelope and nothing else, so a retry renders exactly the message the first attempt would have.

Field		How
Subject line	Shown	The headline and the post title: “Reply, carefully: a relevant post on Reddit: …”.
Post card	Shown	Platform, author and the linked title — no excerpt.
Relevance, subject, sentiment	Shown	Also the preheader most mail clients show in the list.
Reply hint and labels	Shown	Below the card.
Language	Shown	Mailed in the recipient’s interface language; the post title is never translated.
Post body	Never	Never sent: the envelope does not carry it.

[04] TEN PINGS OR ONE/ DIGEST

A burst arrives as one message

Email batches by default. Here 8 posts were held after the first; they arrive together when the window closes, best first.

[05] WHAT WILL BITE YOU/ LIMITS

What email is and is not for

These constraints are mostly ours rather than a vendor’s, which is the honest thing to say about email: there is no API to hit a limit on. What there is instead is a set of things email is bad at. Failures are tracked per channel, so one broken destination never stops the others.

One address per channel, and it must be a verified member of your organization. If three people need alerting, add three channels — each with its own floor. A distribution list or outside address is refused, by design. [source]

The first mention to clear the floor is mailed at once and the rest of a five-minute window arrive as one digest, so the real ceiling is how often FishOut collects: every hour on every plan, and every 15 minutes on Reddit, Hacker News and Bluesky for keywords you mark Fast on a paid plan. [source]

A mail rule is a silent failure. Unlike an archived Slack channel, a filtered inbox returns no error — the channel stays healthy and the deliveries keep counting. This is why the relevance floor matters more here than anywhere else. [source]

Email is the slowest channel to act on. There is nothing to click that assigns or archives — the link goes back to the inbox, where the actual triage happens. [source]

Every one of the thirteen providers, email included, is on every plan including Free. [source]

You see	It means	Do this
email_recipient_not_member	The address is not a verified member of the organization any more.	Invite them again, or point the channel at a current member.
mail_send_failed	The mail provider refused or timed out.	It is retried; if it persists, contact support.
