TL;DR
Journeys stop sending immediately. Any message that was mid‑flight is cancelled and won’t be retried.
Campaigns are automatically paused for up to four (4) days. If you don’t upgrade or your new billing cycle hasn’t started within that window, the queued messages are cancelled. They keep their place in the queue until you have quota again.
You can upgrade to resume sending right away, or simply wait until your quota resets on the next billing cycle.
Notifications appear in the Campaigns UI indicating the pause (see screenshots below).
Why This Happens
Every plan includes a monthly messaging allowance so we can maintain reliable deliverability for all customers. When you reach 100 % of that allowance, we temporarily block further sends to prevent over‑age charges and to protect shared IP reputation.
What You’ll See in the App
Campaigns list
Status column shows Paused for affected campaigns. Hovering the ∙∙∙ menu displays: “You have exceeded your quota. Upgrade in Billing to continue.”
Schedule / Send dialog
Banner states “You’ve exceeded your email quota for this billing cycle. Upgrade your plan to increase your quota.” and the primary button changes to Upgrade to schedule or send.
Journeys
Messages stop at the node that tries to send. There is currently no in‑app banner, but you’ll notice delivery metrics stay at 0.
How to Resume Sending
Upgrade your plan
Go to Billing.
Click Change Plan and follow the checkout flow.
All paused campaigns (and future journey messages) will send instantly after payment is confirmed.
Turn on Auto‑Upgrade (recommended)
Toggle Auto‑Upgrade in the same Billing section.
Next time you reach the limit, we’ll automatically move you to the next tier so sending never stops.
Wait for the reset
If upgrading isn’t an option, no action is required. Your allowance resets at the start of your next billing cycle and sending resumes automatically.
FAQ
Will my paused campaigns lose their schedule?
No. We keep the original schedule and send as soon as quota is available.
Are bounced or failed messages retried after I upgrade?
No, only queued campaign messages retry. Journey messages that were cancelled stay cancelled.
Can I reduce my volume instead of upgrading?
Yes. Delete or reschedule campaigns and pause journeys to bring usage below your cap. You can then wait for the reset.
