FAQ

Everything you want to know.

Will my emails land in Spam?+

No. We send directly through Amazon SES, with every message digitally signed (DKIM, SPF, DMARC). Our confirmed Inbox delivery rate is above 99.8%. You can check your domain right now with the scanner at the top.

How do credits work?+

1 credit = 1 email. Top up any amount (100 lei = 10,000 emails) and send whenever you have offers. Credits never expire and there is no monthly maintenance fee.

Can I change the design however I want?+

100%. Change colours, buttons, images, products — or paste your own HTML. Everything adapts automatically to mobile and Dark Mode.

How hard is it to move from Klaviyo or Mailchimp?+

Not at all. Export your list as CSV and drop it in — or give us access and we do everything for free within 24 hours, including list cleaning.

Do I get a tax invoice?+

Yes. Every payment automatically generates a deductible tax invoice for your company in Romania or the EU.

What is Double Opt-In and why does it matter?+

Subscribers confirm their address with a click in an email. This protects your reputation, keeps you GDPR-compliant and significantly increases open rates. The form comes ready-made.
