Trust

Protect your domain, your data, and your customers.

Reputation protection

New free workspaces are reviewed before they can send. Bounce and complaint thresholds throttle bad traffic before it hurts everyone.

Authentication done right

DKIM signing on every send, guided SPF, DKIM and DMARC setup per sending domain, plus a dedicated tracking domain for every workspace.

Credentials and payments handled carefully

Mailbox credentials are encrypted at rest and API keys are stored hashed, never in plain text. Checkout is a hosted redirect to a PCI-compliant payment processor, so card details never reach InBuzzed servers.

Account access is defended

Rate limiting and bot protection sit in front of every authentication endpoint.

A real, accountable company

InBuzzed is operated by Astra Innovations LLC, a registered Florida company based in Sanford, Florida — not an anonymous SaaS. GDPR and CCPA terms are available, with a signed Data Processing Addendum on request.

Abuse is monitored, not ignored

A published Acceptable Use Policy sets the rules, and reports to abuse@inbuzzed.com go to a monitored inbox, not a black hole.

Read our Terms, Privacy Policy, Acceptable Use Policy, DPA and Cookie Policy.

Frequently asked questions

Common questions, straight answers.

What does InBuzzed replace?

InBuzzed replaces the patchwork of tools teams use for transactional email, marketing campaigns, contact management, and delivery monitoring. Instead of separate dashboards for each, you get one workspace.

How are transactional email and broadcasts different?

Transactional emails are triggered by user actions — password resets, order confirmations, onboarding sequences. Broadcasts are sent to a list — newsletters, product announcements, lifecycle campaigns. InBuzzed handles both from the same workspace.

What can I do on the free tier?

Send up to your monthly limit via API or SMTP, manage contacts, build templates, and monitor delivery. Paid tiers unlock broadcasts, webhooks, analytics, and higher volume.

How long does setup take?

Most teams are sending their first email within 15 minutes. Connect via API or SMTP, verify your domain, and you are live. No migration project required to start.

How do upgrades and billing work?

Start on any tier and upgrade instantly as your volume grows. Billing is usage-based within your plan limits. Annual plans cost ten months instead of twelve. Enterprise teams get custom terms.

Ready when you are

Send your first email in the next fifteen minutes.

Free plan, no card. Upgrade when your volume does.
