Question 1

Can I start using Mailbeam today?

Accepted Answer

Access is still by invitation: sign up to join the waitlist and we'll invite you in batches as capacity allows. Once you are in, both the Free plan and the paid plans below are available — billing is live and the prices shown are what you pay. Features marked Roadmap are documented ahead of release and are not available yet.

Question 2

What counts as a verification?

Accepted Answer

One POST request to /v1/verify counts as one verification, regardless of the result (valid, invalid, or unknown). In a batch, each address in the list counts as one verification — submitting the batch itself is free. Requests that fail due to a malformed payload or missing API key do not count against your quota.

Question 3

What happens if I exceed my monthly quota?

Accepted Answer

On the Free plan, requests above 1,000 return a 429 error. On paid plans, overages are billed at your plan's overage rate (e.g., €0.005 per verification on Growth), and you'll receive an email notification when you hit 80% and 100% of your quota.

Question 4

Do unused verifications roll over?

Accepted Answer

No. Your monthly quota resets on your billing anniversary regardless of usage. This keeps billing predictable and avoids quota hoarding. Pay-as-you-go is a better fit if your usage is highly seasonal.

Question 5

Can I change plans anytime?

Accepted Answer

Yes. Upgrades take effect immediately and are prorated to the day. Downgrades take effect at the end of the current billing period. You can also switch between monthly and annual billing without losing your account.

Question 6

Do you charge for duplicate emails?

Accepted Answer

Yes — each API call counts as one verification regardless of whether you've verified the same address before. If you're verifying the same list repeatedly, cache the results on your side. Our response includes a verified_at timestamp.

Question 7

Is there a free trial for paid plans?

Accepted Answer

Yes. Starter, Growth, and Pro include a 14-day free trial with full access to the features shipped at that point, no credit card required to start. You are only charged when the trial ends, and you can cancel from the billing page before then.

Question 8

What payment methods do you accept?

Accepted Answer

We accept all major credit and debit cards (Visa, Mastercard, Amex), SEPA Direct Debit for EU customers, and bank transfer for annual contracts over €2,000/year. All payments are processed by Stripe.

Question 9

Do you offer non-profit discounts?

Accepted Answer

Yes. Registered non-profits receive a 40% discount on any paid plan. Send your registration certificate to billing@mailbeam.dev and we'll apply the discount within one business day.

Question 10

Is invoicing available?

Accepted Answer

Yes. All paid accounts receive a PDF invoice via email on each billing date. EU VAT numbers are automatically validated and applied to invoices. Annual contracts can be invoiced upfront.

Question 11

How does the GDPR compliance work?

Accepted Answer

Mailbeam is designed as a GDPR-compliant data processor. Email addresses you send us are processed in real-time on EU-based servers (Frankfurt) and not stored after the response is returned. Batch jobs are the one exception: the list and its results are kept for 72 hours so you can download them, then deleted automatically. All plans include a Data Processing Agreement (DPA). Scale and Enterprise plans additionally have it signed automatically in the account dashboard.
