FAQ
- Can you fix SPF, DKIM, and DMARC for HubSpot email?
Yes. That is the foundation of most engagements. We configure the records HubSpot requires, validate them in the portal and with external DNS checkers, and confirm alignment on your primary and any secondary sending domains before you resume bulk sends to your full list.
- How long does it take to recover sender reputation?
Authentication fixes can verify within hours once DNS propagates. Reputation recovery depends on how much damage occurred and how consistently you send clean mail afterward — we set expectations based on your bounce and complaint history after the audit, not generic promises or fixed timelines.
- Will fixing marketing email help sales sequences too?
Often yes, if sequences send through connected inboxes on the same domain. Shared reputation means marketing and sales benefit from the same authentication and list discipline, and we review both channels during diagnosis so fixes cover the whole domain, not just marketing broadcasts.
- Do you remove spam traps and bad addresses from our lists?
We help you identify high-risk segments, recommend suppression rules, and configure bounce handling in HubSpot. Bulk list cleaning may involve your data team or a verification vendor — we integrate the result into smart lists and workflows your team can maintain without re-importing spreadsheets each month.
- What if we just migrated to HubSpot from Marketo or Mailchimp?
Migrations are a common trigger for deliverability issues because DNS and warming are skipped. We authenticate the HubSpot sending domain and plan volume ramp-up with warming schedules and staged sends so mailbox providers do not throttle your first big sends after cutover.
- How much does a HubSpot deliverability fix cost?
It depends on how many domains, brands, and list problems we find. We scope and quote after a short review of your DNS and recent send stats — severity ranges from a quick auth fix to a deeper list rehab, and we explain which before any work starts.
