Captain Verify

Let’s be honest: sending an email campaign and watching your bounce rate spike is incredibly frustrating. You’ve put in the work to build your audience, but the reality of the digital world is that data decays fast. People change jobs, use disposable addresses, or simply make typos when signing up. This isn't just a minor technical glitch; it directly hurts your sender reputation and wastes your marketing budget on people who will never see your message. CaptainVerify was born out of a simple mission: to help marketers and developers regain control over their data quality without the usual complexity. We believe that cleaning your email list shouldn’t be a chore or a technical headache. Instead of just giving you a "valid" or "invalid" status, we provide a deep dive into your database, identifying spam traps, risky domains, and catch-all addresses that could put your deliverability at risk. The way we work is straightforward and transparent. You can drop a massive file into our dashboard for a quick cleanup or plug our API directly into your website to stop bad data before it even enters your system. Because we are based in Europe, we’ve built everything with a "privacy-first" mindset. We are fully GDPR-compliant, ensuring that your data is encrypted, processed securely, and deleted once the job is done. We don’t believe in trapping users with complex subscriptions you’ll forget to cancel. Our pay-as-you-go model is designed to be fair, allowing you to scale your verification needs as your business grows. Whether you’re a startup sending your first newsletter or an established enterprise managing millions of contacts, our goal remains the same: making sure your emails actually land where they belong.

ClevMail

ClevMail is an email marketing platform in which an AI agent writes campaigns from a short request. During setup, the business describes what it sells and how it talks to its customers. From then on, a user can ask for a campaign in one sentence. The agent, called Clevi, reads the company website, recent campaigns and the contact list, writes the email together with a generated image, suggests which contacts should receive it and leaves the draft in the account. Every draft passes a set of rules written in code before the user sees it. The rules flag figures that do not appear in the company profile or documents, links without a valid address, placeholders left empty, cliches and subject lines that run too long. They report what they find and do not rewrite the text. Each account sets how much the agent does on its own, on three levels: Suggest, Write drafts and Send for approval. On every level, a campaign written by the agent is sent only after a person presses send. The account also includes a block editor with inbox preview, contact import, tags and segments, automated welcome, WooCommerce abandoned cart and win-back flows, open and click reports, one-click unsubscribe with consent tracking, and a dedicated sending subdomain on every plan. The interface is available in English and Romanian. Prices are in RON, and the free plan has no time limit.
