// quick answer

Sender blocks campaign sending when your active subscribers exceed the plan or you run out of monthly email credits. Remove inactive subscribers (the count updates hourly) or upgrade; email credits reset at the next billing cycle.

Most likely fix: Remove subscribers to get under the limit

How to fix it

// try these in order, the most common fix is first

  1. FIX 1Remove subscribers to get under the limit

    1. 01Subscribers > filter unsubscribed, bounced and long-inactive contacts
    2. 02Delete them; the active count recalculates every hour
    3. 03Retry the send
    Did this fix it?
  2. FIX 2Upgrade the plan

    1. 01Account settings > Billing > Change or renew plan
    2. 02Pick a larger subscriber tier
    3. 03On a yearly plan, buy a larger yearly plan
    Did this fix it?
  3. FIX 3Avoid the automatic renewal upgrade

    1. 01Before renewal, check the active subscribers meter on the Billing page
    2. 02Trim the list, or turn off auto-renewal if you do not want to be moved to a pricier tier
