Contacts & templates
Build clean lists and reusable templates so every campaign sends faster.
Importing contacts
Go to Contacts → Import and upload a CSV with at least an email column. Optional columns: first_name, last_name, plus any custom fields you define.
- Headers are matched case-insensitively.
- Duplicates (by email) are skipped — the original record is kept.
- Invalid or unsubscribed addresses are rejected during import and shown in the result summary.
Custom fields
In Contacts → Fields add a field (text, number, date). Reference it in templates with {{field_key}}. Empty values fall back to whatever default you set in the template.
Templates
Open Templates → New template. Each template has a name, subject, HTML body and plain-text body. Save and reuse it from any campaign.
Merge tags
Use double-curly syntax anywhere in the subject or body:
Hi {{first_name}},
Your account at {{company}} is ready.
— The RAPID SMTP teamBuilt-in tags: {{first_name}}, {{last_name}}, {{email}}, {{unsubscribe_url}}, {{current_year}}.
Suppression list
Anyone who unsubscribes or hard-bounces is added to the suppression list automatically. To exclude additional addresses, paste them into Contacts → Suppressed.
Best practices
- Send only to people who opted in. Buying lists destroys deliverability quickly.
- Re-engage or remove subscribers who haven't opened anything in 6+ months.
- Keep a plain-text version of every HTML email — spam filters reward it.
- Personalize at least the subject or first line; bland mass mailings get flagged.
