How to contact Ostro support

For account and payment questions, email support@tryostro.com or use the contact form to send your enquiry directly to the right team. Provide an email address where we can reply. You do not need to open an email application to submit the form.

After a successful submission, the form shows a confirmation and submission reference. If it reports a problem, your message stays in the form so you can try again. Avoid closing the page until you have a confirmed outcome. You can also email the team directly.

Contact Ostro first for questions about your Ostro service. We can coordinate with the relevant financial partner when needed. The payer may still need to ask their own sending bank for a trace or payment reference.

Include useful context

Use your registered email where possible. Describe what happened, when it happened and the step or status you see. For payment questions, include the reference, amount, currency and payment date.

If you already have an email thread about the issue, reply in that thread to keep the context together. Avoid opening multiple enquiries for the same payment.

Leave sensitive information out

Do not include passwords, authenticator codes, private keys, seed phrases, identity documents or complete financial records in your initial message.

Support will explain any further evidence required and the appropriate way to provide it.

Other contact types

Pricing enquiries can go to hello@tryostro.com. Privacy requests can go to privacy@tryostro.com, and suspected security issues to security@tryostro.com.

This help center does not offer live chat or promise an instant response. Email is the direct support channel.
