Local-first means the campaign workspace and much of the processing happens on your machine, while messages still travel through the SMTP or provider services you configure. That gives you more control over operational data, but it does not transfer responsibility for the recipients, content, or sending practices away from you.
Confirm the legal basis for the audience
- Record where each contact came from and why you are allowed to contact them.
- Do not treat a public address, scraped address, or purchased list as automatic consent.
- Document the audience, purpose, and retention period for each campaign.
- Honor regional requirements such as CAN-SPAM, CASL, GDPR, CCPA, and applicable local rules.
Make every message easy to identify and stop
- 1Use an accurate From identity and a monitored Reply-To address.
- 2State who you are and why the recipient is receiving the message.
- 3Include a working unsubscribe path that does not require a reply or login.
- 4Process opt-outs promptly and keep them in a durable suppression list.
- 5Do not re-enroll a suppressed contact through another list or sequence.
Review the campaign before sending
| Review area | Question to answer |
|---|---|
| Audience | Is every recipient relevant, permissioned, and outside suppression? |
| Identity | Are the From, Reply-To, company, and contact details accurate? |
| Content | Does the message make a truthful claim and provide a clear next step? |
| Tracking | Are the pixel, links, redirect, and unsubscribe endpoints working? |
| Schedule | Is the timing appropriate for the audience and region? |
| Recovery | Do you know how to pause, stop, or suppress the campaign if signals worsen? |
Local does not mean invisible
Your provider, tracking endpoints, DNS services, and webhook integrations may still process operational data. Review those providers’ policies and configure only the connections your workflow needs.
Keep records without keeping everything forever
Export campaign results, contacts, suppression records, and sending logs when a business or compliance process requires them. Store those exports securely, restrict access, and define a retention period so old recipient data does not accumulate without purpose.
Use operational safeguards
- Protect SMTP credentials with the operating system keyring or another secure secret store.
- Use attachment and template paths that stay within the intended workspace.
- Limit tracking and webhook access to authenticated endpoints.
- Review provider sending limits and acceptable-use policies before increasing volume.
- Pause sending when complaints, bounces, or provider warnings change materially.
