PaperTube Marketing Email Domain Setup

Overview

To protect PaperTube's primary domain sender reputation, all outbound marketing emails will be sent from a dedicated subdomain: papertube.pro. This isolates cold/marketing traffic from the main papertube.co domain, reducing the risk of deliverability degradation if marketing sends generate spam complaints or low engagement.

This setup was decided during the ^[1] and is a prerequisite for launching the Account Engagement email campaigns tied to the ^[2].

Configuration Decisions

Why sam@?

The name "Sam" was chosen deliberately — it is gender-neutral and does not correspond to any existing PaperTube employee's primary email address (the only Sam on staff uses samantha.a@papertube.co). This avoids confusion while keeping the sender name human and approachable.

Why a separate domain?

The leads being emailed are sourced from third-party data (not inbound opt-ins), making this effectively a cold outreach list. Sending cold campaigns from the primary papertube.co domain risks:

• Spam complaints degrading domain reputation
• Deliverability issues affecting transactional and relationship emails sent from the main domain

Using papertube.pro as a dedicated marketing domain contains any reputation impact.

Technical Setup Steps

Owned by Mark Hope (mark.hope@asymmetric.pro).

1. Purchase domain — Register papertube.pro via preferred registrar.
2. Create mailbox / forwarding rule — Set up sam@papertube.pro with no active inbox; configure auto-forward of all inbound replies to parag@papertube.co.
3. Configure DNS records — Add SPF record authorizing Salesforce Account Engagement mail servers to send on behalf of papertube.pro. DKIM and DMARC records are also recommended for improved deliverability.
4. Add domain to Account Engagement — Register papertube.pro as a verified sending domain within the Salesforce Account Engagement instance.
5. Send test emails — Send internal test messages from sam@papertube.pro, verify:
   - Emails land in inbox (not spam)
   - Reply-to routing forwards correctly to Parag
   - Tracking pixels and links resolve properly

Do not send the first live batch until all tests pass.

Downstream Dependencies

This domain setup is a blocking dependency for:

• Account Engagement email campaigns — Emails cannot be built and sent until the verified sending domain is in place.
• Sales follow-up warm lead track — The multi-touch nurture sequence described in ^[3] will send from this domain.
• First email batch target — Approximately February 13, 2026 (one week after landing pages are finalized).
