Replies dropped? Check the 3 prime suspects.

The old spray-and-pray approach is dead. When performance slips, it's almost always one of these.

01Relevance
Too much preamble before the value
Personalisation that isn't relevant
Outdated or unverified data
02Infrastructure
Sending from your primary domain
Skipping warm-up
Not monitoring live campaigns
03Efficiency
Outdated tech stack
SDRs juggling prospecting and closing
Manual work that should be automated

The playbook shows you how to fix each one.

What's inside

The rules behind every Flowd campaign.

No theory. The exact numbers our deliverability team works to, so you can copy them.

01 / INFRASTRUCTURE

Protect your main domain.

How we set up alternative domains and inboxes, and the SPF, DKIM and DMARC checks we audit.

0
Cold emails from your main domain
02 / SEND VOLUME

Send like a human.

Throttle sends through the day and space them per company, so spam filters see steady, natural behaviour.

45 min
Between sends per inbox
03 / MONITORING

Know when to rest a domain.

The weekly health check on spam rates, blacklists and bounces, and the point we replace a domain.

1.5%
Reply rate floor per domain
04 / RELEVANCE

Write emails worth opening.

Segmentation, personalisation beyond the first name, soft CTAs and a real Flowd script, line by line.

2x
Replies from one personalised campaign
