If your SendX account becomes locked after adding new contacts, don’t worry — this is a temporary safeguard, not a suspension or data loss. It simply means your total contacts have gone beyond the limit of your current plan.
During this time, all your data, campaigns, and automations remain safe. Only sending is paused until you choose to upgrade your plan or adjust your contact list.
This article explains why the lock occurs, what you can still access, and how to quickly restore full functionality so you can continue sending without interruption.
Before You Begin
Ensure you know your current plan tier and contact limit.
Access to your billing page in SendX.
Any changes to contacts or plan upgrades should be done carefully to avoid accidental lockouts.
Step-by-Step Instructions
Check Your Contact Count:
Navigate to your SendX dashboard and review your total contacts.
Compare this with your current subscription tier limit.
Identify the Trigger:
Adding contacts beyond your tier triggers the account lock.
You may notice that sending emails is limited (only a few test emails can be sent), but all other features remain accessible (templates, forms, automations).
Resolve the Lock:
Option 1: Upgrade Plan
Go to your billing page → Select the next tier → Complete payment.
Option 2: Reduce Contacts
Delete enough contacts to fit within your current tier → Contact SendX support to unlock the account.
If recently imported contacts triggered a lock — for example, if you accidentally uploaded a CSV file that exceeded your contact limit — please delete the excessive contacts to bring the count back within your plan’s limit and maintain your current billing tier.
Important: Unlocking will occur automatically in case of an upgrade payment. After taking one of these steps. If the account continues to be unlocked, please contact support to remove the sending limitation.
Tips & Best Practices
Monitor your contact count regularly to avoid unexpected locks.
Only add contacts that are opted-in and engaged to maintain deliverability.
Be mindful of account upgrades — confirm contact counts before importing large lists.
Keep billing information up-to-date for smooth plan adjustments.
Conclusion
When your account locks after adding contacts, it’s simply a reminder to review your plan limits. It's not a permanent restriction. Once you upgrade to the right tier or reduce your contact count, you can restore full sending access within minutes.
Keeping an eye on your contact growth helps you stay within limits and avoid future interruptions. And if you’re ever unsure what caused a lock, the SendX support team can help you get back on track quickly.
