Deliverability is the marketer's problem but the platform's infrastructure. This page explains how Hober's sending actually works, what protects your reputation from other tenants, and how to warm up a new sending domain — stated plainly, including the limits of where we are today.
How Hober sends email
Hober delivers email through SendGrid, authenticated as your sending domain — SPF, DKIM, and DMARC belong to you, not to a shared Hober identity. The per-channel deliverability panel in the dashboard checks your domain authentication status directly and shows the exact DNS records to verify, and our own transactional domains run the same SPF/DKIM/DMARC setup we ask of you.
Responsibility splits cleanly:
- You own domain authentication and list quality — who you import and how you got their consent.
- Hober owns everything after the send button: suppression enforcement, consent checks, bounce and complaint processing, one-click List-Unsubscribe headers, and the feedback loops into your dashboard.
What protects your reputation
- A per-tenant suppression ledger. Bounces, spam complaints, and unsubscribes are recorded per tenant and enforced on every subsequent send. A suppressed address is not "less likely" to be contacted — it is structurally excluded at dispatch.
- Consent enforced at send time. Every message — including ones an AI agent proposes — passes the consent, quiet-hours, and frequency-cap guardrail before delivery. Withdrawn consent suppresses immediately.
- Standards-compliant unsubscribes. RFC 8058 one-click List-Unsubscribe headers and human-readable preference links ship on every marketing email, which is what mailbox providers now expect from senders.
- Visible health. The deliverability dashboard shows your per-channel delivery rate, bounce and complaint rates, and trend — the same numbers we watch, with warning thresholds at 2% bounces and 0.1% complaints.
The honest limit: Hober tenants currently send from SendGrid's shared IP pools. Your domain reputation is yours alone; IP reputation is shared with the pool. Dedicated IP options and inbox-placement testing are on the roadmap — until then, the suppression and consent enforcement above is what keeps the pool healthy, and it applies to every tenant equally.
Warming up a new sending domain
- Authenticate before anything. Verify SPF and DKIM in the channel's deliverability panel first. Sending unauthenticated mail is the fastest way to teach providers to distrust the domain.
- Start with your most engaged segment. First sends should go to recent openers/clickers or fresh signups — recipients likely to engage, which is the signal providers read.
- Ramp volume gradually. A practical schedule: hundreds per day in week one, doubling every few days as metrics hold. Avoid a first-week blast to a cold, imported list — that pattern looks identical to spam.
- Watch the dashboard thresholds. If bounces exceed 2% or complaints exceed 0.1%, pause the ramp, clean the segment, and let the metrics recover before resuming.
- Keep suppression on. Never re-import or work around suppressed addresses; the ledger is protecting the domain you are warming.
Other channels, briefly
Push reputation is token hygiene, not IPs: invalid tokens are detected and fed back into deliverability automatically. SMS reputation is carrier filtering: STOP replies are recorded as opt-outs the moment they arrive. WhatsApp is template approval and the 24-hour window, both enforced at send creation.
