Subscription plans

MailSlurp subscriptions combine a base plan with optional add-ons so you can scale from small test workloads to large production messaging programs.

How subscriptions work​

Each account starts on a base plan. Your base plan includes monthly quotas for key resources, such as:

  • Inboxes created per month
  • Emails created/sent per month
  • API usage and related platform limits

If your workload exceeds the included quotas, you can enable add-ons. Add-ons are billed monthly based on your configuration and usage.

Base plan vs add-ons​

Base plan:

  • Sets your core included monthly capacity
  • Defines standard account capabilities and limits

Add-ons:

  • Extra inbox/email capacity beyond base quotas
  • Phone number capabilities
  • Additional user seats for team access
  • Additional storage and other account extensions

For current plan tiers and add-on pricing, use the MailSlurp pricing page.

Upgrade your account in the app​

To upgrade:

  1. Sign in to the dashboard.
  2. Open the pricing/subscription area.
  3. Select the plan that matches your expected monthly usage.
  4. Confirm the upgrade and billing details.

Enable and manage add-ons​

After selecting a base plan, configure add-ons to match your workload profile.

Typical add-on workflow:

  1. Open subscription management in the dashboard.
  2. Enable required add-ons (for example extra inbox/email capacity, phone numbers, seats, storage).
  3. Review projected monthly cost.
  4. Save changes and verify limits/usage in your account.

Billing management and invoices​

Manage billing from the dashboard billing area (Settings > Billing).

From billing settings, you can:

  • View billing history and invoices
  • Change plans
  • Open the billing portal for payment and profile updates

In the billing portal you can update:

  • Payment method
  • Billing address
  • Billing contact and invoicing email
  • Tax/business details (where applicable)

Usage statistics and monitoring​

Track usage in the dashboard usage area (/usage) to monitor trend lines and avoid unexpected overages.

Use the usage page to:

  • View account usage over time
  • Compare current usage against plan limits
  • Plan upgrades/add-ons before large campaigns or test runs

Subscription operations checklist​

  1. Estimate monthly inbox, email, SMS, and storage needs.
  2. Choose a base plan for normal expected traffic.
  3. Enable add-ons for burst capacity or specific features.
  4. Review usage weekly/monthly and adjust plan before limits are hit.
  5. Keep billing contacts and payment methods current.
