A sequence that is running on paper but not actually sending is almost always one of a handful of things, and you can usually rule them out in under five minutes. Start by checking which channel is stuck, because TikTok DM sequences and email sequences fail for different reasons.
Quick answer
For TikTok DM sequences, the usual causes are the weekly outreach quota hitting zero for the creator levels you are targeting (it resets Sunday), no creators left inside your filters, a stuck state that a restart clears, TikTok rate-limiting, or an expired TikTok auth token. For email sequences, the first thing to check is different: the email domain integration must be connected, because Hubfluence sends email from your own domain and not from a Hubfluence address. Also confirm your audience actually has emails on file and that you have monthly email allowance left.
If it is an email sequence, check these first
Email sequences do not run on the TikTok API, so the TikTok checks below do not apply to them. Work through these instead:
Is the email domain integration connected? Open Settings, Apps and Integrations and confirm it is connected and green. This is the single most common reason an email sequence looks live but sends nothing. Hubfluence will not send creator outreach from a Hubfluence address, so without an authorized sending domain there is nothing to send from.
Does your audience actually have emails? An email sequence can only reach creators with a public email on their profile in our database. If you built the list with filters that do not require an email, most of it may be ineligible. Use the email filters in Social Intelligence or AI Creator Search, or pick the email outreach sequence flow, which filters for creators with an email automatically.
Do you have monthly email allowance left? Your plan sets the monthly cap: 3,000 creator emails on Growth, 9,000 on Business, 15,000 on Enterprise. Sending stops once the cap is reached.
Is your DNS set up? A domain missing SPF, DKIM, and DMARC can send and still get filtered, which looks like "not sending" from the creator's side. See the email domain setup article.
If replies are the problem rather than sends, that is the Gmail workspace integration, which is separate. Both connections are covered in How do I connect my email to send outreach sequences?
1. Check your weekly outreach quota
This and everything below applies to TikTok DM sequences. TikTok caps how many new creator messages and Target Invites your shop can send per week, and since October 2026 that cap is set per creator level. L0 and L1 creators are unlimited for every seller, while L2 Gold through L7 draw on an allowance based on your rolling 30-day GMV.
That means a sequence targeting Gold or higher can stop cold while another sequence targeting L0 and L1 keeps running. Check the quota counter on the home page. If the level you are targeting is at or near zero, the system is doing exactly what it should, and the fix is waiting for the Sunday reset or widening the sequence to include lower levels.
2. Check you still have creators in your filters
If your targeting is narrow or you have already messaged most creators that fit your filters, the sequence can run out of eligible accounts and stop sending. This happens often on older sequences or heavily filtered lists. Widen the filters or point the sequence at a fresh list.
3. Stop and restart the sequence
If quota and creator availability both look good, stop the sequence and restart it from the dashboard. A restart forces the system to re-fetch product data, refresh audience filters, and re-establish its connection to the TikTok API, which clears the most common stuck states. A large share of "not sending" tickets resolve with a clean restart alone.
4. Rule out TikTok-side rate limiting
Sometimes TikTok slows or pauses outreach depending on messaging volume, API load, or platform-side restrictions. In those cases the sequence may still look active, but sends are temporarily throttled in the background until the limit cools off.
5. Reconnect your TikTok Shop integration
If your auth token has silently expired (which occasionally happens after inactivity or a TikTok API change), the sequence can look active while every send call fails behind the scenes. Go to Settings, Integrations, disconnect TikTok Shop, then reconnect using the secure auth flow. Restart the sequence once the integration shows green and outreach should resume within a few minutes.
