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

Open a campaign and go to Settings. Daily limits shows the real number for each channel — emails, LinkedIn messages, LinkedIn invitations, WhatsApp — that this campaign may send per day, per connected account.
Campaign daily limits

Each channel's number, with the ceiling written underneath it

The line under each box tells you the ceiling your accounts allow. Yena’s account-safety defaults are 25 emails, 25 LinkedIn messages, 10 LinkedIn invitations and 20 WhatsApp messages per account per day. Invitations are the strictest of the four on purpose: LinkedIn tolerates far fewer invitations than messages, and whatever you send by hand counts against the same informal ceiling. A new mailbox starts lower while it warms up — 10 a day in its first week, 20 in its second — and the line says so for as long as that lasts. A campaign can go below these numbers, never above. Type a bigger one and it snaps back to what the account allows, with a plain sentence naming the limit and who can raise it. Set a channel to 0 to pause it for this campaign while the others keep running. When the day’s number is reached, the people still waiting 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.
