Some campaigns stopped scheduling sends. The full chain from draft to validation, billing, scheduling, and delivery has been fixed and checked end to end, and meeting slot-offers, replies, and follow-ups are drafting reliably again.
What changed
A number of campaigns got stuck somewhere between a draft being written and an email actually going out. Sends weren't getting scheduled, even in cases where everything upstream, the draft itself, its approval, looked fine on the surface. This turned out to trace through several distinct stages of the pipeline a draft moves through before it becomes a delivered email: draft approval, content validation, billing checks that confirm the send is covered, the scheduler that decides when it goes out, and finally delivery itself.
Each stage of that chain has been fixed individually, and the fix was verified end to end rather than at any single point in isolation. That distinction matters: it's possible to fix one stage of a pipeline like this and still have campaigns get stuck at a different stage that looks fine until you actually trace a real draft all the way through it. This fix was checked by following real drafts through the entire chain, from the moment they're written to the moment they're delivered, to confirm nothing else was quietly breaking along the way.
That verification specifically covered campaigns offering meeting time slots, which depend on precise scheduling to be useful at all, along with campaigns handling replies and follow-ups, which depend on the same chain working correctly every time a contact responds or a sequence advances. Drafts for all of these now generate reliably and flow through validation, billing, and scheduling to an actual delivered send.
How to use it
There's nothing to do to benefit from this fix directly. If you had a campaign that had stopped scheduling sends, check its status now: it should be scheduling and sending normally, including any meeting slot-offers, reply drafts, or follow-ups that were part of it.
If you're not seeing that, check the campaign's activity log for any specific error message tied to a contact or a send before reaching out, since a genuinely new issue would show up there differently than the stuck-scheduling pattern this fix addressed. Most campaigns affected by the underlying issue should now be moving through the full pipeline without you needing to intervene at all.
Why it matters
A campaign that silently stops sending is worse than one that fails loudly with a clear error, because nothing in your view tells you it's stopped until you happen to notice the symptoms yourself, replies have gone quiet longer than they should, a meeting slot offer never actually reached a contact who was ready for one, or a follow-up that should have gone out days ago never did. By the time you notice, you've often already lost the momentum with whoever was affected.
Fixing and verifying the whole chain, rather than just the symptom that was most visible or most frequently reported, matters because a partial fix would have left some campaigns still stuck at whatever stage wasn't addressed. Verifying meeting slot-offers, replies, and follow-ups specifically, rather than just first-touch drafts, means the fix holds across the different ways a campaign actually uses this pipeline, not just the simplest case.
The meeting slot-offer case deserves particular mention, since it's the most timing-sensitive use of this pipeline. Offering a prospect a specific slot to meet only works if the offer actually reaches them and the follow-through, confirming, rescheduling, sending a reminder, keeps working after it. A break anywhere in the chain from draft to delivery turns a meeting offer that looked sent from your side into one the prospect never actually saw, with no signal back to you that anything went wrong until the meeting simply doesn't happen.
Checking campaigns that depend on fast replies
If you run campaigns that depend heavily on replies and follow-ups moving quickly, for example a sequence built around booking meetings within a specific window, it's worth reviewing recent activity on those campaigns now to confirm sends are landing on the schedule you expect. Most campaigns affected by the underlying issue should already be caught up, but if a specific campaign still looks off, checking its activity log for a real error is a better next step than assuming the same stuck-scheduling issue is still present.
Going forward, this fix doesn't change anything about how you build or run a campaign. Draft, validation, billing, scheduling, and delivery all continue to work the way they're supposed to; this was about making sure they actually do that reliably, end to end, rather than changing what any of those stages does.
What to expect from here
An outreach system is only as reliable as its weakest connection between stages. A campaign can have a perfectly good draft, pass validation, clear billing, and still fail to send if the handoff into scheduling breaks, and from your side that failure is indistinguishable from a campaign that simply has nothing left to send. Verifying the full chain end to end, rather than fixing and declaring done at whichever stage seemed most likely responsible, is what it actually takes to trust that a campaign showing as active is going to keep sending.
For campaigns that stalled during the period this issue was present, the practical outcome is straightforward: contacts who were waiting on a meeting offer, a reply, or a follow-up that never arrived should now be moving again, with the same draft quality and timing you'd expect from a campaign that was never affected. There's no separate action needed to re-enable a previously stuck campaign; the fix applies automatically to how the whole pipeline processes it going forward. If you were holding off on relying on a campaign type that seemed unreliable during this period, meeting slot-offers in particular, this is the point at which it's worth trusting it again. Build and run campaigns the way you always have; the reliability of the pipeline underneath them is what changed here, not anything you need to do differently on your side.
Availability
This applies to all campaigns, including those using meeting slot-offers, reply handling, and follow-up sequences.
