# Campaign won't activate

Why the Activate Campaign button stays disabled in Victoria AI, and how to clear each kind of blocker.

## Campaign won't activate: the Activate Campaign button is disabled

The readiness window lists at least one failed check. **Activate Campaign** stays disabled until every failed check passes; warnings alone don't disable it.

**Fix:** read each red line, select its **Fix →** link, correct the problem, then turn the campaign switch on again to re-run the checks. [Preflight checks](https://docs.versionseven.ai/help/preflight-checks) explains every message.

## Campaign won't activate: the sequence checks fail

The most common blockers are on the **Sequence** tab: an empty sequence, an email with no subject or body, a LinkedIn message with no text, a variable with a typo, or `{{double_braces}}`. With A/B testing on, Variation B is checked too.

**Fix:** open **Sequence**, fill in every step, and use single braces such as `{first_name}`. Check Variation B with the **B** button.

## Campaign won't activate: the sender checks fail

"No accounts assigned", "Sequence has LinkedIn steps but no LinkedIn account is assigned", "assigned accounts are no longer active", or an account "also active in" another campaign.

**Fix:** open **Settings → Connected Accounts** and select accounts that cover every channel the sequence uses. Reconnect disconnected accounts on **Sender Accounts** ([Reconnect a sender](https://docs.versionseven.ai/help/reconnect-a-sender)), and pause the other campaign or pick a different account when one is already in use.

## Campaign won't activate: email domain check fails

"failed the email authentication check" means the mailbox's domain is missing an SPF or DMARC record, or has a broken one.

**Fix:** correct the DNS record named in the message with your domain provider, then re-run the check on **Sender Accounts**. See [DNS setup](https://docs.versionseven.ai/help/dns-setup).

## Campaign won't activate: lead checks fail

"No leads enrolled", too many leads missing data for a variable, or too many leads the sequence can't reach (no email for an email-only sequence, no LinkedIn URL for a LinkedIn-only one).

**Fix:** add leads on **Leads**. For missing data, enrich or re-upload the leads, remove them, or remove the variable. For unreachable leads, add steps on the missing channel or remove those leads.

## Campaign won't activate: subscription or billing check fails

"Payment failed", "Trial has ended", "Subscription is canceled", "set to cancel at period end", or more active accounts than your plan covers.

**Fix:** open **Credits & Billing** and update the card, reactivate the plan, or add seats. See [Failed payments](https://docs.versionseven.ai/help/failed-payments) and [Free trial](https://docs.versionseven.ai/help/free-trial).

## Campaign won't activate: "Couldn't check readiness"

The check didn't complete, so nothing was activated.

**Fix:** select **Retry**. If it fails again, close the window, wait a minute and turn the switch on again.

## Campaign won't activate from the Copilot or an AI assistant

The Copilot and connected assistants use the same checks. They answer with the failing checks instead of activating, and they ask before activating with warnings.

**Fix:** ask the assistant which checks failed, fix them as above, and ask it to activate again.
