Campaigns send from your accounts — your work inbox, your LinkedIn profile. Yena’s job is to make automated outreach indistinguishable from careful manual outreach, so those accounts stay healthy.

​
Daily limits

Each sender account has a daily sending limit per channel. LinkedIn connection requests have their own, stricter limit — LinkedIn tolerates far fewer invitations than messages, and your manual activity counts against the same informal ceiling. When a campaign reaches the day’s limit, remaining people simply wait. Their status says so, and they go out in the next delivery window. Nothing is lost or skipped.

​
Human pacing

  • Messages go out inside your delivery window, on business days if you keep that setting on.
  • LinkedIn and WhatsApp actions are spaced out with small randomized gaps rather than fired in a burst — a pattern of instant, evenly-timed actions is exactly what platforms flag.
  • One campaign never monopolizes an account: limits are counted per sender account, across all campaigns using it.

​
The do-not-contact list

Your workspace has a do-not-contact list. People on it are never sent a campaign step, in any campaign. Yena also maintains it automatically:
  • Replies — a person who replies exits all campaigns (see Track progress and replies).
  • Bounces — when an email hard-bounces because the address no longer exists, Yena records the address as undeliverable and stops sending to it. Temporary failures and out-of-office replies do not count.
You can review and manage the list in your workspace settings.

​
Email signatures

Email sent through a provider’s API does not automatically get the signature you set in Gmail or Outlook. Yena stores a signature per connected mailbox and appends it to every campaign email:
  • Google accounts — import your existing Gmail signature with one click, or paste one.
  • Microsoft accounts — Microsoft does not expose signatures, so paste yours once in Settings → Connected Accounts.
If your company adds a footer to all outgoing mail at the server level, leave the signature in Yena empty to avoid double-signing.

​
Good practice

  • Start small. A short sequence to a well-chosen list outperforms a long chain to a broad one — and teaches you what works before you scale.
  • Warm up new mailboxes. A freshly created email account should not send at full volume on day one.
  • Write like a person. Personalization fields help, but the preview is the real test: read the rendered message and ask whether you would reply to it.
  • Respect a no. If someone declines, add them to the do-not-contact list so no future campaign reaches them.
