Skyp gives you control over how recipients can opt out of your campaign emails, and handles suppression automatically in the background so you don't accidentally email anyone who has asked you to stop.

When this setting is turned on (the default), every email Skyp sends for that campaign ends with a single-sentence opt-out prompt — for example:

"Not relevant? Reply 'no' and I won't follow up."

This gives recipients a clear, polite way to say they're not interested. Skyp uses AI to classify replies, so any reply that clearly means "no" — whether the recipient types "no", "not interested", "please stop", "wrong person", or something similar — automatically adds them to your suppression list. They won't receive any further emails from your account, on that campaign or any other.

The exact wording of the opt-out line varies from message to message. Skyp rotates across roughly 20 different phrasings that all mean the same thing (reply, and I'll stop). The variant chosen for a given message is deterministic — the same message always uses the same phrasing, even if a send is retried — but different contacts and different follow-ups in the same campaign will see different wordings.

You don't need to configure this. The rotation exists to keep the sentence from becoming a fixed content fingerprint that spam filters can pattern-match against across the whole platform, without changing the meaning of the prompt.

The label below the toggle confirms what your emails will include. The change takes effect immediately and applies to future sends for that campaign. You can turn the line off if your emails already include a custom opt-out message, or if the prompt feels out of place for a particular campaign.

Skyp reads every reply to a campaign email and classifies its intent. When a reply is classified as an opt-out:

You can also manually add contacts or entire domains to your suppression list from Do Not Contact.

Can I see who has opted out?
Yes — replies classified as opt-outs appear in Inbox, and suppressed contacts are visible in your Do Not Contact list.

What happens if I turn off the opt-out line?
The one-sentence opt-out prompt will not be added to emails for that campaign. Skyp will still classify inbound replies and automatically suppress any contact who clearly asks to stop — the opt-out line just makes that ask easier for the recipient.

Why does the exact wording of the line change between emails?
Skyp rotates across many equivalent phrasings so the opt-out line doesn't become a fixed piece of text that spam filters can key on across the whole platform. Each message gets one variant, chosen deterministically from the message, and the meaning is identical every time.
