Three coordinated workstreams: stabilize and repair the marketing sender that reaches your subscribers, run the marketing program fully on Pardot, and stand up a separate, compliant cold-outbound channel that protects your brand domain — all watched in one monitoring layer.
Based on a public DNS & authentication review of vernier.com plus your program details. These are the root causes that lead to blacklisting and inbox-placement loss.
Salesforce Marketing Cloud, Pardot, Mixmax, Zendesk, WP Engine and a dedicated IP all send as vernier.com. When one stream complains or hits a trap, the whole domain reputation pays for it.
3–6 emails per week across a ~500k database mixes highly-engaged subscribers with old, unengaged, and possibly purchased contacts — the fastest route to spam complaints and spam-trap hits.
Prospecting and rented-list activity (e.g. an Agile list synced into Salesforce) sent from vernier.com puts your core brand domain at the center of cold-email risk. This is the single biggest reputation threat.
SPF is using all 10 permitted DNS lookups — any further change risks an SPF failure. Under your strict p=reject policy, that means legitimate mail can be rejected. Fixable, and a quick early win.
With multiple platforms touching the same contacts, unsubscribes and bounces aren't guaranteed to sync everywhere — so people may keep getting mail they opted out of, which drives complaints.
You already run p=reject DMARC with active reporting, a dedicated IP, and published DKIM. The structure is mature — it needs consolidation and hygiene, not a rebuild.
Stabilize what talks to subscribers, take the marketing program off overlapping tools and run it fully on Pardot, and move all cold activity to its own protected infrastructure.
Repair reputation and protect the people who actually want your email.
One system of record for marketing — no more overlapping streams colliding.
Move all prospecting off vernier.com onto its own warmed infrastructure.
Engaged subscribers keep receiving value at a healthier cadence. Unsubscribed contacts are honored and suppressed everywhere — never re-mailed. The large dormant/unknown segment is handled separately through careful re-permission, not blasted — which is what protects the recovered reputation.
A self-contained outreach engine that never touches your brand domain's reputation — data in, verified, sequenced, sent from dedicated domains, and monitored end to end.
Separate sending domains so cold activity can never damage vernier.com.
Every inbox is warmed over 3–4 weeks before it sends a single prospect.
Volume ramps to ~2,000 sends/day across the inbox fleet, within safe per-inbox caps.
Reputation, blacklists and authentication tracked continuously with alerts.
Brand-adjacent domains used only for outreach, each with its own authentication and warmed mailboxes. Shortlist (availability confirmed):
| Domain | Status |
|---|---|
| vernierscience.com | available |
| verniersci.com | available |
| vernieredu.com | available |
| tryvernier.com | available |
| meetvernier.com | available |
| vernier-science.com | available |
Volume is built from many small, safe senders rather than one risky one:
| Lever | Target |
|---|---|
| Sending domains | 6–8 |
| Mailboxes per domain | 6–8 |
| Sends per mailbox / day | ~30–40 (after warmup) |
| Warmup ramp | 3–4 weeks |
| Steady-state output | ~2,000 / day |
Each prospect moves through a five-touch sequence; any reply routes out of automation to a human.
Short, relevant first touch — context and a single clear reason to reply.
A useful resource or insight tied to their world. No pressure.
Relevant proof point / outcome that makes the offer credible.
A different hook for those who didn't connect with the first.
Polite break-up that often earns the reply. Then auto-suppress.
Data is prepared and verified on our side before anything is sent — bad data never touches the warmed inboxes.
Sourced / supplied prospect data, incl. review of rented sources (e.g. Agile).
Syntax + MX validation, mailbox verification, remove role / catch-all / disposable.
Spam-trap screening, dedupe, and match against global suppression.
Enriched, segmented, verified — only clean records enter the sequence.
A dedicated monitoring layer watches every domain and IP — brand and cold — so problems are caught before they cost you the inbox.
Powered by our bulk blacklist checker (Spamhaus DBL + multi-RBL) plus authentication and placement tracking. Live status of monitored assets:
| Asset | Type | Blacklist (DBL/RBL) | Auth (SPF/DKIM/DMARC) | Status |
|---|---|---|---|---|
| vernier.com | brand domain | monitoring | SPF at limit | remediation |
| dedicated IP (Salesforce) | sending IP | monitoring | aligned | repair |
| vernierscience.com | cold domain | clean | to set up | provisioning |
| verniersci.com | cold domain | clean | to set up | provisioning |
| vernieredu.com | cold domain | clean | to set up | provisioning |
Stabilization and the cold-channel build run in parallel; consolidation follows. Checkpoint with your team in the last week of July.
Public review complete. Provision access (Postmaster, SNDS, Salesforce/Pardot reports, suppression exports) to confirm internal data.
Delisting, SPF fix, frequency reduction, engaged/dormant segmentation, suppression cleanup.
Move marketing onto Pardot, unify suppression, fix alignment, establish governance & reporting.
Register dedicated domains, set authentication, begin mailbox warmup, build the data-cleaning pipeline.
Ramp cold to ~2,000/day, monitoring fully live, sequence optimization on reply data.
Review reputation recovery, cold-channel performance, and agree the next growth phase.
