Cold emailing Brazilian companies: setup, templates and rules
To cold email Brazilian companies effectively: send from real mailboxes with SPF, DKIM and DMARC, keep volume low per mailbox (dozens a day), write in Brazilian Portuguese, keep it short and specific to the segment, send 3 to 4 follow-ups that stop on reply, include an easy opt-out, and rely on LGPD's legitimate interest basis when you use personal data. Pair email with WhatsApp, which Brazilian SMBs answer much faster.
Technical setup
- SPF, DKIM and DMARC on the sending domain. Since 2024, Google and Yahoo require sender authentication, and bulk senders also need one-click unsubscribe and low spam rates.
- A secondary domain to protect your main one.
- Warm-up: start with a few sends a day and ramp over weeks.
- Volume per mailbox: dozens per day; scale with more mailboxes, not more sends per mailbox.

Follow-ups and tooling
Many replies arrive after the first email. Send 3 to 4 follow-ups over 2 to 3 weeks, each with a new angle, and stop on reply. 1Lead connects Gmail or Microsoft mailboxes (or uses managed sending infrastructure on paid plans with automation), finds the companies by CNAE, writes the Portuguese copy with AI, and stops the sequence when the lead replies.
