Email deliverability
Deliverability starts with who you write to. hubsell keeps volume low to mid and targeted, sends from your own mailbox with authentication set up by our team, keeps to a daily cap and sending window, and verifies every contact the day you reach out.
Cold email deliverability
Inbox placement
Emails go out from your own Google Workspace or Microsoft 365 mailbox through its API, with no outside server or tracking redirect in the path.
SPF, DKIM and DMARC are set up with you by the hubsell team, so mail providers can check that your email really comes from you.
Your mailbox has a daily cap and a sending window, and the flow stops for a contact as soon as they reply or an email bounces.
Email deliverability checklist
Each of these is handled in hubsell, so reaching the inbox is not left to your reps.
Emails go out from your Google Workspace or Microsoft 365 account through its API, not from a shared server that filters already distrust.
Protects: Your sender reputation
The hubsell team sets up the three records with you, so mail providers can confirm that your messages really come from your domain.
Protects: Your domain
Every address is checked the day it is used, catch-all domains included, so few emails bounce and providers see a clean list.
Protects: Your bounce rate
Your mailbox sends a limited number of emails a day, so volume never spikes and draws attention.
Protects: Each sender
Emails go out within the hours you set, spaced out over the day, the way a person sends mail.
Protects: Your timing
When a contact replies or an email bounces, the flow stops for that contact, so nobody gets a follow-up after answering.
Protects: The buyer’s goodwill
Links are not rewritten through a tracking domain, which keeps your emails looking like ordinary mail.
Protects: Your inbox placement
hubsell is built for low to mid volume: fewer emails, sent to people who fit your ICP and have a reason to hear from you. Targeted outreach gets replies, and replies build your sender reputation.
Protects: Your conversion
How it works
The work email is generated and validated the day you reach out, catch-all domains included.
The email goes out from your connected mailbox, within its daily cap.
Emails are spaced out within the sending window you set, through the Google or Microsoft API.
Replies and bounces end the flow for that contact. Everyone else moves on to the next step.
Data quality and deliverability
Most deliverability problems start before the first email is sent. Old lists are full of people who have changed jobs, and every bounce tells mail providers that your email is not wanted.
hubsell sources contacts when you need them and verifies each email the same day, so you write to people who hold the role today, at addresses that exist.
Relevant, recent data also earns replies, and replies are the strongest sign to a mail provider that your email belongs in the inbox.

Email deliverability FAQ
Email deliverability is whether your email reaches the recipient’s inbox, rather than the spam folder or nowhere at all. It depends on how you send, the reputation of your domain and the quality of the addresses you write to.
The usual causes are shared sending servers, missing SPF, DKIM or DMARC records, addresses that bounce, sudden spikes in volume and messages nobody replies to. hubsell addresses each of these.
It sends from your own mailbox through the Google or Microsoft API, sets up SPF, DKIM and DMARC with you, keeps to a daily cap, sends within your windows, stops on replies and bounces, and verifies every contact the day it is used.
Yes. Emails go out from your Google Workspace or Microsoft 365 mailboxes through their APIs. There is no outside SMTP server and no tracking redirect in the email.
The hubsell team sets them up with you during onboarding, so your domain passes the checks mail providers run before your first campaign goes out.
Yes. Your mailbox has a daily cap. hubsell is built for low to mid volume: a smaller number of emails to well-targeted contacts converts better than a large number to a broad list.
Yes. You set sending windows, and emails go out within them, spaced out over the day rather than all at once.
The flow stops for that contact. Nobody gets a follow-up after answering, and a bad address is not tried again.
Every bounce hurts your sender reputation. hubsell verifies each email the day it is used, catch-all domains included, and 95% of work emails are accurate, so far fewer emails bounce. See enrichment.
Because targeted outreach converts. Fewer emails to people who fit your ICP and have a reason to hear from you get more replies, and replies tell mail providers that your email belongs in the inbox. Sending to a broad list does the opposite.
