If you’ve been managing your contacts and suddenly realize you’re running out of space, it's a great sign that your list is growing. You can upgrade and increase your contact limit directly from your SendX billing page in just a few steps.
Upgrading is a manual process, so you stay in control of when and how the change happens. This article walks you through how to choose the right tier, complete the upgrade, and make sure your sending continues without interruption.
Before You Begin
Know your current plan tier and contact limit.
Access to your SendX billing page.
Ensure your payment method is active for seamless upgrades.
Step-by-Step Instructions
1. Check Your Contact Count
Click on the profile icon → Billing → Plan Details.
Compare your total contacts against your current plan limit.
Determine how many additional contacts you need to accommodate.
2. Upgrade Your Plan
Select Team billing and click on “ Change Plan.”
Select the new plan tier that fits your contact count. And click on Update plan.
Confirm payment using your active card.
The billing will display your previous plan,
your currently purchased plan, and the due date.
For example, if you initially purchased a $9.99 plan and then upgrade to a $19.99 plan, the billing system will charge you only the difference—$10—since $9.99 has already been paid for the previous plan.
3. Avoiding Account or Team Lockouts
If you add contacts before upgrading, your account may lock temporarily.
Best practice: Upgrade before importing new contacts.
If your account is locked, only 10 test emails can be sent; all other features remain accessible.
4. Downgrades and Billing Adjustments
Click on profile icon → Billing → Downgrade Plan.
Downgrades take effect immediately in the system but will only reflect on the next invoice.
No prorated refunds are issued for the current 30-day billing cycle.
Make sure to manually downgrade to avoid being charged at a higher tier.
Tips & Best Practices
Regularly monitor your contact count to anticipate upgrades.
Upgrade promptly to avoid account lockouts and ensure uninterrupted email sending.
For any billing concerns, review your invoices and contact SendX support if adjustments are needed.
Keep your payment method updated to avoid failed transactions.
Conclusion
Once your upgrade is complete, your SendX account unlocks automatically, and your new contact limit applies right away. All campaigns, automations, and data remain exactly as they were — the only change is your expanded capacity. Going forward, review your contact count periodically so you can plan future upgrades on your own schedule and keep your sending uninterrupted.
