Why an agent isn't sending
Last updated: October 3, 2026
When an outreach agent isn't sending, it's usually waiting for something, out of creators, stopped by a limit, or stopped by an error from TikTok. Start with the agent's Status on Outreach > Outreach Agents, then find your case below.
Where to find it
- Each agent's row shows its Status: Running, Stopped, Error, or Restarting. Hover over Error to read the message. The agent's page shows the same message as Agent Error.
- The Activity Log on the agent's page lists the invitations it sent, marked Sent or Failed, and its conversations.
- Target Invites Sent and Messages + Follow-ups Sent, at the top of the page, count what your agents sent in the last 24 hours.
Running but not sending
- The Euka TikTok Shop app isn't authorized. In the markets where the app is available, invitations go only through it. Without it, or once its authorization lapses, agents that send invitations stay Running, send none, and show no error. Authorize the app as described in Connect your TikTok Shop.
- It's outside its sending hours. A clock icon next to Running means the agent is outside its Time Range.
- It reached its Daily Sending Limit. It carries on as the 24-hour window moves.
- Your brand reached its plan's daily limit. Agents that send invitations wait, and carry on as the 24-hour window moves. See Plans and limits.
- Other agents are taking their turn. Running agents take turns, and a high-priority agent gets about half of them.
- There's no one new to contact. A segment agent waits for creators to enter its segments, and an agent with follow-ups still scheduled stays running to send them.
- TikTok is refusing new invitations for now. We wait about an hour, then try again.
- Your Shop has 10,000 active target collaborations. A target collaboration is TikTok Shop's invitation for a creator to promote your products. Delete invitations no creator has accepted, as described in Outreach agents.
- You've just started or edited it. It can take a few minutes.
If the agent sends but skips creators you expected, see Who an agent contacts.
Stopped without an error
An agent stops without an error message when:
- It ran out of creators. We email you. See Who an agent contacts.
- Your plan's message allowance is used up. We email you, and you can't start the agent again until the count resets or you upgrade. See Plans and limits.
- We can't sign in to your TikTok Shop. After more than two days without access, we stop your agents. Fix the connection, then click Resume. See TikTok Shop connection problems.
- TikTok keeps rejecting its invitations because the creators or products are unavailable, and the agent has few creators left.
- Someone on your team paused it.
The automatic retry
Every 12 hours, at 00:00 and 12:00 UTC, we set agents in Error back to running so they try again. If the problem is still there, the agent goes back to Error. Agents that show Restarting are restarted automatically too.
Agents stopped by TikTok's weekly outreach limit are the exception: they stay stopped until you click Resume. Once you've fixed the cause of an error, you can click Resume instead of waiting for the retry.
Errors and what to do

| Invalid target collab name or message…, or invalid message | TikTok rejected the Invitation Name or the Target Collaboration Description. | Remove emojis, links, and blocked words. Try the text in TikTok Shop's Affiliate Center to find what TikTok rejects, then edit the agent. |

| TikTok rejected the seller phone number as invalid… | TikTok refused the contact phone number on the invitation. | Contact us at support@euka.ai. |
| Target collab invites cannot be sent because this shop is on TikTok Managed Service. | TikTok doesn't let Managed Service Shops send target collaboration invitations. Every agent that sends invitations stops, but DM (direct message) agents keep going. | Only TikTok can change this. |
| Please activate a paid subscription or contact support | Your brand has no active plan. | Choose a plan in Settings > Brand > Billing, or contact us at support@euka.ai. |
When you click Resume
- For Subscription required to start agents, Upgrade your plan, or CRM limit reached, see Plans and limits.
- Setup Affiliate Manager means your TikTok Shop isn't verified in Euka yet. See Connect your TikTok Shop.
- For Target collaboration expiry date has passed, edit the agent and set a new Valid Until date.
- For Agent has no creators left to message, widen the agent's filters, add creators to its list, or create a new agent.
How to check a product in TikTok Shop
When an agent says a product is out of stock or unavailable:
- In TikTok Shop's Affiliate Center, start a new target collaboration invitation yourself.
- Try to add the product. TikTok shows why it can't be added.
- Hover over the product's status. A reason can show there even when the status says Eligible.
- Check that the product is in stock and active, that your Shop has no violations blocking new collaborations, and that Holiday Mode is off.
If Low Shop Experience Score Detected shows on the page, your Shop's experience score limits your ability to reach creators until it improves.
What only TikTok can fix
- TikTok sets your weekly outreach limit and tier, and the cap of 10,000 active target collaborations. Only more affiliate GMV raises your tier.
- For error 16024048, TikTok has to repair its contract data for the product.
- TikTok doesn't let Managed Service Shops send target collaboration invitations.
- Only TikTok can lift restrictions it puts on your Shop, such as those for violations or a low Shop experience score.
A product's stock, status, and LIVE auction setting are yours to change in TikTok Shop. For the rest, contact TikTok Shop's seller support.
FAQs
Will my agents start again after the weekly limit resets?
No. Click Resume on each agent once the limit has reset.
My agent shows Running but sent nothing today. Why?
It's waiting for its sending hours, a daily limit, its turn, or new creators. The list under "Running but not sending" covers each case.
How long does an error take to clear?
We retry most errors every 12 hours. If you've fixed the cause, click Resume to try again right away.
Why did my agent stop without an error?
It ran out of creators, your plan's message allowance ran out, or we lost access to your TikTok Shop. In the first two cases, we also email you.
Why did all my agents stop at once?
If they show Error, it's usually TikTok's weekly outreach limit. It stops every running outreach agent in your Shop, but not CRM agents, so check TikTok Weekly Outreach at the top of the page.
If they show Stopped, your plan's message allowance may be used up, or we may have lost access to your TikTok Shop.
