Generic cold email is dead and everyone knows it. The fix is a pipeline that researches each lead and writes a personalized opener at scale. Here is how to build that in n8n, and the one-click way to run it in PhewDo.
What you are building
Here is the shape of the workflow.
New lead in listTrigger
A new row or webhook kicks off the pipeline.
Enrich the leadHTTP
Pull company, role and a recent signal to write from.
Write the openerOpenAI
Ask the LLM for a one-line personalized opener from the signal.
Send and trackEmail
Send through your sender and track opens and replies.
How to build it in n8n
The magic is in the prompt and the data you feed it. Four nodes.
- Trigger node. Start from a new lead in your sheet, CRM or a webhook.
- HTTP Request node. Enrich the lead with company and role data plus a recent trigger event.
- OpenAI node. Prompt the model to write a single personalized opening line, not the whole email.
- Email node. Merge the opener into your template and send through your warmed sender.
- Tracking. Log opens and replies back so you can branch follow-ups.
The catch is deliverability and warm-up, which n8n does not handle, plus you own the LLM key, the prompt and every failed run.

See PhewDoFrequently asked questions
Which model should I use?
A mid-size model is plenty for a one-line opener. You are classifying and summarizing, not writing essays.
Why only personalize the opener?
The first line earns the read. Over-personalizing the whole email gets slow and expensive without lifting replies much.
How is the PhewDo version different?
PhewDo handles enrichment, AI personalization, warm-up and sending in one place, so you skip the keys and the deliverability work.
