One credit pool across Find, Verify, Send, AI, and Agent · Invalid emails are never charged · Need 25,000+ credits? Talk to sales

One pool. Five ways to spend it.

Every credit works the same way, wherever it's spent — whether a person clicks the button or an agent calls the API.

Agent add‑on

Starts at $0. Scales when your agent does.

Every plan ships with MCP server and skill.mdaccess included, free. If an agent runs past your plan's monthly threshold, extra usage is metered from the same credit pool — you'll always see it coming.

  • ✓ No separate contract or minimum to unlock it
  • ✓ Same deliverability and data as the human‑facing UI
  • ✓ Usage alerts before anything is metered

Running more than 25,000 credits a month?

Custom mailbox limits, dedicated support, and volume pricing for teams and agencies at scale.

Pricing, answered.

What is a credit?

A credit is spent on one verified or found email, one AI-assisted write, or one send/reply handled by the Agent add-on. Find, Verify, Send, AI, and Agent all draw from the same pool — there's no separate "actions" currency to track.

Do unused credits roll over?

No. Credits reset each billing cycle on every plan, including Free, and don't carry over to the next month.

Are invalid or undeliverable emails charged?

No. AskOptimus only charges a credit for emails that come back deliverable or risky. Invalid and undeliverable addresses are never charged.

What's the difference between monthly and annual billing?

Annual billing is the same plan at 30% off, billed once a year instead of monthly. You can switch between monthly and annual anytime from account billing.

Can I upgrade, downgrade, or cancel anytime?

Yes. Plan changes take effect immediately and are prorated. Cancellations take effect at the end of the current billing period, with no long-term contract.

Is the Free tier free forever?

Yes. Free includes 50 credits a month, one mailbox, and MCP server access, with no expiration date and no credit card required.

What does the Agent add-on cost?

The Agent add-on is free to start and draws from your existing credit pool. Usage past your plan's monthly threshold is metered, and you're notified before any charge.

Do you offer custom or enterprise pricing?

Yes. Teams needing more than 25,000 credits a month, custom mailbox limits, or dedicated support can talk to sales for a custom plan.

No credit card. 50 credits forever. Bring your team and your agents.
