Deliverability
Great targeting means nothing if the message never arrives. hubsell protects the whole path to the inbox: verified contacts, authenticated sending from your own mailboxes, and volume paced to keep your reputation intact.
Emails send through the Google and Microsoft APIs, straight from your own mailboxes, with no external relay in the path.
Every contact is verified the moment it is sourced, catch-all domains flagged, so bounces stay low.
Volume is spread across your sender profiles within safe limits, so a new domain is never blasted into a filter.
Each address is checked at the point of use, not pulled from a list captured months ago. Catch-all domains are flagged before you send, so you spend credits on contacts that can actually receive mail.
Outreach goes through the Google and Microsoft APIs directly from your own accounts. There is no third-party server in the path for filters to distrust, so your sending looks like what it is: real mail from a real person.
SPF, DKIM, and DMARC are the checks providers run to decide if mail is really from you. hubsell guides you to set all three correctly, so your domain passes and your messages are trusted.
Volume is spread across sender profiles and ramped within safe limits. A new domain warms up instead of spiking, so you build reputation rather than burning it on the first send.

FAQ
The average tenure of a B2B decision-maker is roughly 2.5 years, meaning static CRMs and purchased lists decay by 25 to 30% annually. hubsell solves this with zero-day sourcing, our live-data method: we source and verify contact data at the exact moment of your request, which keeps accuracy high and protects your sender reputation.
hubsell's infrastructure is "entirely not present" in the sent email. We do not use external SMTP servers or spam-triggering redirect links for tracking. Emails are sent via direct API integration (Google/Microsoft), resulting in significantly higher open rates.
Most sales intelligence tools hand you a static export and leave the outreach to another platform. hubsell sources contacts live at the moment of your request — then lets you reach out via email, LinkedIn, and phone and sync everything to your CRM, all without switching tools. No database decay, no duct-taped stack.
