Frequently Asked Questions

Find answers to common questions about email verification.

Does GDPR apply if I am not based in the EU?

Yes. GDPR applies based on recipient location, not where your business is incorporated. Any company emailing EU residents must comply.

What is the difference between CAN-SPAM and CASL?

CAN-SPAM allows you to email without prior consent as long as you honor opt-outs. CASL requires documented consent before the first send, applies to anyone emailing Canadian recipients regardless of where they are based, and allows individuals to sue senders directly for damages.

Can I use a purchased email list?

No. Purchased lists violate GDPR and CASL directly and generate high spam complaints under CAN-SPAM. The compliance and deliverability cost always outweighs the volume benefit.

How quickly must I process an unsubscribe?

Australia: 5 working days. US and Canada: 10 business days. EU and UK: immediately. Best practice is to automate instant processing across all markets.

Are transactional emails exempt from these rules?

Generally yes, but only if they contain no promotional content. Adding a discount code or product recommendation to an order confirmation can strip the transactional exemption under CASL and GDPR.

Is double opt-in legally required?

Only in Germany, under courts' interpretation of valid GDPR consent. It is strongly recommended across all EU markets and provides the strongest available proof of consent everywhere else.
