Try the free web tools, or connect LookValid to your workflow through the API or MCP server. Sample lookup: email address `ana@example.com`. Syntax: Valid; Domain: example.com; Mail servers: None, null MX record; Disposable domain: No; Free provider: No; Deliverability: Undeliverable. The address is written correctly, but example.com publishes a null MX record, which means the domain accepts no email. Mail sent to this address cannot be delivered. ## Know what you’re signing up for. - **Public pricing.** See the plans and what they include before you sign up. - **Product documentation.** Read how the product works and decide whether it fits your needs. - **A clear way to get help.** Find product support on each website, or contact Meralume Labs with questions about the portfolio.

This policy covers the Meralume Labs website at meralume.com. Each brand in the portfolio runs its own site and publishes its own privacy policy there. ## What we collect The site is informational. It has no accounts, no sign-in, no forms and no checkout, so we collect very little. ### Server logs Our hosting provider, Vercel, serves the site. Like any web host it receives your IP address, browser and device details, the page you asked for and the time of the request, and keeps standard server logs for a limited period. We use them to keep the site running and secure. ### Email you send us Every contact link on the site opens your own email program addressed to hello@meralume.com. If you write to us we keep your message, your address and our replies so we can answer you and keep a record of the conversation. Our support desk reads that inbox and uses AI tools to help sort messages and prepare replies. Please do not send card numbers or passwords by email. ### What we do not collect We do not run analytics, advertising pixels, session recordings or tag managers on this site, and we do not buy or build marketing lists from visitors. ## Cookies and tracking We set no advertising cookies and do no cross-site tracking. The site loads no analytics, pixels, tag managers or third-party embeds, and the site code sets no cookies. Fonts and scripts come from the site itself. Because there is nothing to choose, the site shows no cookie banner. ## How we use it - To serve the pages and keep the site secure and working. - To read and answer the messages you send us. - To keep the records the law requires us to keep. We do not sell personal information and we do not share it for advertising. ## Who else handles it - Vercel hosts the site and holds its server logs. - Our email provider hosts the hello@meralume.com inbox. - Authorities, when the law requires us to hand information over. The brands in our portfolio keep their own records of their own customers under their own privacy policies. A brand site is separate from this one. ## Your rights and how to use them Because this site has no accounts, the personal data we hold about a visitor is limited to server logs and any email correspondence. These rights apply to that data. ### Everyone - Ask for a copy of the personal data we hold about you. - Ask us to correct data that is wrong. - Ask us to delete your data. - Ask for your data in a portable format that you can take elsewhere. ### California Under the California Consumer Privacy Act you have the right to know what personal information we hold, to ask us to delete it, to ask us to correct it, and to opt out of the sale or sharing of your personal information. We do not sell or share personal information, so there is nothing to opt out of. We will not treat you differently for using any of these rights. An authorized agent may make a request for you, and we may ask for proof that they act for you. ### European Union and United Kingdom If you are in the EU or the UK you have the right of access, rectification, erasure, restriction of processing, portability and objection. You also have the right to complain to your local data protection supervisory authority. In the UK that is the Information Commissioner's Office at [ico.org.uk](https://ico.org.uk). ### How to ask - Email [hello@meralume.com](mailto:hello@meralume.com) from the address you want us to look up. - We confirm it is you by replying to that address, and we ask for no more than we need to find your data. - We answer within one month. For California requests we answer within 45 days. Where the law allows, we may extend that period and will tell you why. - A few records may have to be kept even after a deletion request: security logs, and billing and tax records where a transaction exists. Billing records for a product sit with the brand you bought from. We tell you what we kept and why. ## Changes and contact When we change this policy we update the date at the top of the page. Questions about it go to [hello@meralume.com](mailto:hello@meralume.com). ## Related - [Meralume Labs: software for sales, marketing and operations](https://meralume.com/index.md) - [Terms of use: using the Meralume Labs site and its brands](https://meralume.com/terms.md) --- Source: https://meralume.com/terms Last updated: 2026-10-21 # Terms of use: using the Meralume Labs site and its brands The rules for using the Meralume Labs website, who owns its content, and where each brand's own terms and refund terms live. These terms cover the Meralume Labs website at meralume.com. By using the site you agree to them. ## Using the site The site is free to read. It describes our studio and the businesses in our portfolio. Use it lawfully, and do not interfere with it, overload it or try to get into parts of it that are not public. ## Our brands have their own terms Each business in the portfolio runs its own site and publishes its own terms, its own privacy policy and its own refund terms there. If you buy from a brand, those terms govern your purchase, not these. These terms never change what a brand has told you at checkout. - [LookValid](https://meralume.com/brands/lookvalid.md): Data validation API, free tools - [VoiceDeliver](https://meralume.com/brands/voicedeliver.md): AI voicemail drops for sales - [TrialValid](https://meralume.com/brands/trialvalid.md): Card checks at trial signup - [ColdMeetings](https://meralume.com/brands/coldmeetings.md): Cold email that books meetings - [BlogAutoPost](https://meralume.com/brands/blogautopost.md): AI blog autopilot for SEO - [InboxNight](https://meralume.com/brands/inboxnight.md): Overnight AI inbox assistant - [QuitRadar](https://meralume.com/brands/quitradar.md): Early resignation-risk alerts - [ColdAgentAI](https://meralume.com/brands/coldagentai.md): AI cold email platform - [NumberBurn](https://meralume.com/brands/numberburn.md): Burner phone numbers on demand - [ViewPayout](https://meralume.com/brands/viewpayout.md): View bounties that pay creators - [CoinReceipts](https://meralume.com/brands/coinreceipts.md): Crypto call leaderboard ## Ownership The text, design and code of this site belong to Meralume Labs. You may read it, link to it and quote short passages with a link back. You may not copy the site or present it as your own. Names and marks of other companies belong to their owners and appear only to say what a product is or does. ## Links to other sites The site links to brand sites and to other sites we do not run. We do not control them and are not responsible for what they say or do. ## No warranty The site and everything on it is provided as it is and as available, without any promise that it is complete, current, always available or free of errors. Nothing here is advice, and nothing here is an offer to sell you a product; an offer is made only on a brand's own site. ## Limit of liability To the fullest extent the law allows, Meralume Labs is not liable for any indirect, incidental, special or consequential loss, or for lost profit or data, that comes from using or not being able to use this site. Nothing in these terms limits a liability that the law does not allow us to limit. ## Changes and contact We may change these terms by posting a new version here with a new date. Using the site after that means you accept the new version. Questions about these terms go to [hello@meralume.com](mailto:hello@meralume.com).
