The outboundplaybook.

DNS guides, dedicated SMTP explainers, deliverability deep-dives and outbound campaign playbooks from the CloudJet team.

The mailbox warmup playbook: from zero to 40 sends a day

A week-by-week ramp schedule, the signals to watch, and the mistakes that quietly cap your volume.

The three DNS records every sending domain needs, what each one proves, and how to set them up in ten minutes.

Personalization that reads like research, not a mail merge — with real examples from high-performing sequences.

Why spreading volume across many senders beats pushing one domain hard — and how to structure it.

Intent labels, snippets and hand-offs that turn a flood of replies into a pipeline your team can work.

Primary vs. promotions vs. spam: what the numbers mean and which ones should change your sending plan.
