Your SendX subscription is based on a contact tier you choose in advance. You select a tier that fits your expected contact count, pay upfront, and can send unlimited emails to contacts within that limit.
When you'll need this
Refer to this article when you want to understand how SendX pricing works, check your current plan and contact usage, upgrade or downgrade your tier, view past invoices, or update your payment method.
How SendX billing works
SendX uses prepaid, tier-based pricing. You choose a contact tier based on how many contacts you plan to have, and you pay for that tier at the start of each billing cycle. Every tier includes unlimited email sends.
Choosing your tier
When you upgrade from the free trial, you select a contact tier. This tier determines how many contacts you can have in your team before your team gets locked. Choose a tier that covers your expected peak usage for the month.
For example, if you currently have 8,000 contacts but plan to import 3,000 more during a product launch, select the 15,000 tier to avoid interruption.
What counts as a contact
Every unique email address in your team counts toward your tier limit. This includes:
Active subscribers
Unsubscribed contacts
Contacts who marked you as spam
Hard bounced emails
The only exception is duplicates. If the same email address appears in multiple lists, it counts once.
Why unsubscribes and bounces count
These contacts still exist in your database and consume storage and infrastructure resources. If you want to reduce your contact count, you'll need to delete these contacts rather than just unsubscribing them.
What happens if you exceed your tier
If your contact count exceeds your chosen tier, your team gets locked immediately. This can happen during an import or if contacts are added through forms, integrations, or other sources.
When your team is locked:
You can still log in and access all your data
You cannot send emails or campaigns
Scheduled campaigns will not go out
You'll see a banner explaining the lock and prompting you to upgrade
To unlock your team, you have two options:
Upgrade your tier to one that covers your current contact count
Delete contacts until you're back within your current tier's limit
Both options unlock your team immediately.
Viewing your current plan and billing details
1. Click your profile icon in the top-right corner
2. Select Team Billing from the dropdown
3. You'll see your current tier, contact count, and billing summary
4. You can note the contact usage bar to see the exact percentage used
Upgrading your tier
If you need space for more contacts, you can upgrade anytime.
Go to Profile dropdown → Team Billing
Click Change Plan
3. Select a higher contact tier
4. Click Update Plan and confirm on the Stripe checkout page
You'll be charged a prorated amount for the remaining days in your billing cycle. Click View details to see the exact breakdown before confirming.
The proration details show your new plan charge minus a credit for your previous plan's unused days.
Downgrading your tier
If you've reduced your contact count and want to pay less, you can downgrade to a lower tier.
Go to Profile dropdown → Team Billing
Click Change Plan
Select a lower tier
Important: You can only downgrade to a tier that covers your current contact count. If you have 12,000 contacts, you cannot downgrade to the 10,000 tier. You'd need to delete contacts first.
When you downgrade mid-cycle, the unused portion of your current tier payment is credited to your account and applied to future invoices.
Updating your payment method
Go to Profile dropdown → Team Billing
Click Update Payment Method
4. Enter your new card details in the Stripe form
5. Click Subscribe to save the new payment method
Changes apply immediately to future charges.

Your monthly price depends on the tier you choose. Here are common tiers:
Contacts | Monthly Price |
1,000 | $9.99 |
2,500 | $19.99 |
5,000 | $39.99 |
10,000 | $59.99 |

Important notes
Choose your tier based on expected peak usage. If you plan a large import mid-month, select a tier that covers it in advance.
Tier changes are manual. SendX never automatically upgrades or downgrades your tier.
Usage notifications. You'll receive alerts at 80%, 90%, 95%, 99%, and 100% of your tier limit so you can upgrade before getting locked.
Imports never fail. Even if an import exceeds your tier, the contacts are added. Your team then locks until you upgrade or delete contacts.
Common questions
Why was my team locked?
Your contact count exceeded your tier limit. Go to Team Billing to see your current count and either upgrade or delete contacts to unlock.
Do unsubscribed contacts count toward my limit?
Yes. All contacts in your database count, including unsubscribes, bounces, and spam complaints. To reduce your count, you need to delete these contacts.
Can I get a refund if I downgrade?
Downgrade credits are applied to your account for future billing. They're not refunded to your payment method.
What happens to scheduled campaigns if my team locks?
They won't send. Unlock your team before the scheduled time to ensure your campaigns go out.
I accidentally imported too many contacts. What should I do?
Either upgrade to a tier that covers your new count, or delete the excess contacts. Both options unlock your team immediately.
How do I switch between monthly and annual billing?
When changing your plan, you can toggle the billing interval in the plan selection modal to see annual pricing options.
