Outbound deliverability program for Seersite
A managed sending layer beneath HubSpot. Cold outreach moves off the domain the business runs on. The sales workflow stays as it is.
The decisionSeersite × Existantly
Take seersite.com out of cold outreach. Change nothing else.
Today, cold outreach and core business email share one domain. This program moves cold email onto four dedicated domains on Existantly infrastructure, connected into HubSpot. Jack keeps working in HubSpot. Replies still arrive in his inbox and on the contact record.

The problemSeersite × Existantly
One domain is doing two jobs that work against each other.
Mailbox providers score every sending domain continuously. Cold outreach produces the signals that lower the score: low engagement, spam reports, bounces. When cold outreach and core business email share a domain, the business email inherits the damage.
At riskInbox placement for every email Seersite sends from seersite.com: customer replies, investor updates, partner threads, contracts.
How it showsCold outreach that stops getting replies regardless of messaging, and eventually ordinary emails landing in spam.
Why it hidesGoogle and Microsoft do not publish domain reputation. Seersite sees the effect in HubSpot before it sees the cause.

If nothing changesSeersite × Existantly
Every domain used for cold email wears down eventually. The question is which domain.
On a dedicated sending domain, wear is an operating cost: the domain gets replaced and outreach continues. On seersite.com, the same wear reaches the inbox of every customer, investor and partner Seersite emails, and there is no swapping the company's primary domain.
The program puts that wear on domains built to carry it, with backups warming from day one to take over.

The solutionSeersite × Existantly
A dedicated sending layer, invisible from inside HubSpot.
Jack runs sales alone and HubSpot is the system of record. A second tool or a second inbox would not get used, so the program is built around that. HubSpot remains the only interface. Four dedicated domains, each with a live mailbox connected to HubSpot and backup mailboxes warming alongside, sit underneath it.
DomainsFour dedicated .com domains, chosen by Seersite, on Existantly infrastructure.
ConnectionAutomated between HubSpot and the sending mailboxes. Manual emails and drip sequences route through them instead of seersite.com.
RepliesEvery send carries a reply-to on Jack's primary address. Replies land in his inbox and on the HubSpot contact record.

How it worksSeersite × Existantly
Four steps. Jack touches one of them.
1
Work in HubSpot as usual
Manual emails and sequences are written and launched in HubSpot.
2
Validate before send
An email validation integration set up inside HubSpot screens contacts before they are emailed.
3
Send through dedicated mailboxes
Manual emails and sequences send through the dedicated mailboxes instead of seersite.com.

Replies return to Jack
Reply-to on his primary address. Replies land in his inbox and on the HubSpot record.

What the recipient seesSeersite × Existantly
A normal email, and a normal reply.
The outbound message comes from a Seersite-chosen domain. When the recipient replies, the message threads into the same conversation and arrives from Jack's seersite.com address. The reply-to mechanism is a standard setting built into most CRMs and support platforms.
Existantly recommends turning off open and click tracking on cold sends. Tracking pixels work against deliverability.

ScaleRoughly one million emails per month through Existantly infrastructure.
Track recordSeven years operating in cold email and B2B outbound.
Warm-upOne partner used for more than three years, currently warming over 50,000 mailboxes for Existantly.
IP reputationHybrid configuration that shares the sending reputation of established enterprise senders.
Sending policyTwo weeks minimum warm-up, then 5 to 10 to a ceiling of 25 sends per mailbox per day, spaced about 15 minutes apart.
ContinuityBackups warm from day one. When a domain tires, a backup takes its place. Replacement is included.

Commercial termsSeersite × Existantly
Setup once. Then $300 a month.
That is the cost of keeping seersite.com out of cold email. Everything on the previous slide is covered by these two numbers.
| Item | Covers | Amount |
|---|
| Setup | Domain registration, DNS and authentication, mailbox provisioning, warm-up, HubSpot integration and validation setup. | $2,000 one time |
| Infrastructure subscription | Sending infrastructure, mailboxes, continuous warm-up, enterprise IP reputation and replacements. | $300 / month |
| First month | | $2,300 |
Billed monthly, cancel anytime. More volume is $50 per month for each additional 150 sends a day. Seersite owns the domains. Mailboxes and infrastructure stay with the subscription, the same way Google Workspace works.
