Privacy Policy

This policy explains what information Mailstream collects on this site, how we use it, and the choices you have. It covers this marketing site (lp.mailstream.app). By using the site you agree to the practices below.

Information we collect

• Information you give us. When you submit a form, we collect the details you enter, such as your name, email address, and company, plus anything you type in the message field.
• Usage and device information. As you browse, we and our analytics providers automatically collect information such as your IP address, browser and device type, pages viewed, referring URL, and interactions with the page.
• Advertising identifiers. If you arrive from an ad, we may receive click identifiers (for example a Google click ID or Meta click ID) and campaign parameters so we can measure ad performance.

How we use it

• To create and follow up on your account or request.
• To send you related emails, such as account setup and follow-ups.
• To measure and improve our marketing, including matching conversions to the ads that drove them.
• To operate, secure, and improve the site.

Analytics, advertising, and session recording

We use the following third-party services on this site:

• Google Analytics 4 and Google Ads — website analytics and ad conversion measurement.
• Meta Pixel and the Meta Conversions API — ad measurement and optimization. Some conversion data (for example a hashed version of your email) may be sent to Meta from our servers to match your action to an ad. Values used for matching are hashed.
• Microsoft Clarity — we partner with Microsoft Clarity to capture how you use our site through session recordings and heatmaps. Recordings are configured to mask form input values and other sensitive data. Microsoft uses this data per its own privacy statement and terms.

Cookies

We and the services above use cookies and similar technologies to run the site, remember your session, and measure advertising. You can control cookies through your browser settings; blocking some cookies may affect how the site works.

Sharing

We share the information you submit with the service providers that help us operate, such as our CRM (HubSpot) and email provider (Resend), and with the analytics and advertising services listed above. We do not sell your personal information.

Your choices

You can opt out of Google Analytics using Google's opt-out add-on and manage ad personalization in your Google and Meta account settings. To request access to or deletion of the information you submitted, email us at privacy@mailstream.app.
