Pushbuild

Cold email that keeps its lists tidy, its replies routed and its domains healthy.

Instantly sends the emails. We build what sits on either side: clean lead lists going in, positive replies reaching the right person and the CRM, and regular checks on the DNS and settings that decide whether your mail lands in inboxes. The written scope comes first, and you approve it before we start.

Sound familiar?

What teams sending cold email with Instantly tell us before a project starts.

  • A good reply sat in the Instantly inbox for three days before a salesperson saw it.
  • Our lead lists come from several tools and the same person gets emailed twice.
  • Opens fell off a cliff and nobody can say whether it is the copy, the list or the domain.
  • Closed deals never get marked, so we keep emailing people who already bought.
  • Reporting means exporting four CSVs every Monday.

What we build

Each one is a working piece you can open and check when it's done.

Lead lists in, cleaned first

Lists from spreadsheets, scrapers or a data provider checked for duplicates, role addresses and invalid emails, then loaded into the right campaign with custom fields filled.

Replies routed to the CRM

Interested replies create or update a deal, notify the owner in Slack, and stop further steps in the sequence for that person.

CRM setup and lead pipelines API integrations and data sync

Suppression and do-not-contact lists

Customers, open deals and anyone who asked to stop kept out of every campaign automatically.

Deliverability checks

SPF, DKIM, DMARC and custom tracking domain records reviewed for each sending domain, with a plain list of what to change and a recheck afterwards.

API integrations and data sync

Campaign reporting

Sent, replied, positive and booked by campaign, sender and list source, refreshed on a schedule in a sheet or dashboard.

Dashboards and reporting

Alerts for sender trouble

A message when a mailbox disconnects, bounce rates climb or sending stops, so the cause is looked at the same day.

n8n, Make and Zapier automation

Industries that use it: Marketing agencies, SaaS startups, Recruiting, IT / MSP.

Example projects

Illustrations of the shape of the work, not past clients. Yours gets its own written scope.

Example project

Positive replies into Pipedrive

Example: an agency selling web design runs weekly campaigns. When a reply is marked interested, a deal appears in the pipeline with the email thread linked and the owner pinged in Slack.

Instantly webhooks, Pipedrive, Slack

Example project

List cleaning before upload

Example: a recruiter buys candidate-company lists from two providers. Before loading, a script removes duplicates and anyone already contacted this quarter, and splits the rest by industry.

Python, Google Sheets, Instantly API

Example project

Domain health check on Monday

Example: a lead generation shop with eight sending domains gets a weekly summary of DNS record status and bounce rates per mailbox, with the problem domains at the top.

Questions people ask first

Will you fix our deliverability?

We check the technical settings that are in our hands and tell you what is wrong. Deliverability also depends on your list quality and copy, which we point out but do not rewrite unless you ask.

Do you write the campaigns?

Our work is the setup around them: lists, routing, checks and reports. We can structure sequences for you, but the messaging is yours.

Is this allowed?

Cold email is subject to laws such as CAN-SPAM and to Instantly's own rules. We build unsubscribe handling and suppression into the setup, and you remain responsible for who you contact.

How do we start?

Tell us how leads get into Instantly today and where replies go. We reply with questions or a written scope.
