Maximize Deliverability with SendEmails.com Free Edition
Key points
- Authentication: Set up SPF, DKIM and DMARC for your sending domain (use a custom domain if possible).
- Use verified SMTP integration: Link SendEmails.com to a reputable SMTP provider (Amazon SES, Mailgun, Postmark) when Free Edition allows external SMTP to improve deliverability.
- List hygiene: Remove hard bounces and inactive addresses; run an email verification check before large sends.
- Warm-up & sending cadence: Start with low daily volumes and gradually increase; avoid big blasts from new IPs or domains.
- Segmentation & personalization: Send targeted content to engaged segments and include personalized fields to boost engagement (opens/clicks reduce spam placement).
- Content best practices: Avoid spammy subject lines, minimize heavy images, include plain-text version, and ensure unsubscribe link and physical address are present.
- Monitor metrics: Track bounce, open, click, complaint, and unsubscribe rates; pause campaigns if complaints spike.
- Reputation management: Keep complaint rate <0.1%, bounce rate low, and maintain consistent sending patterns.
- Inbox testing: Before wide sends, use inbox-placement tests (or send small samples to major providers) to check where messages land.
- Free Edition limits & workarounds: If the Free plan restricts features (sending volume, custom domain, SMTP), prioritize authentication, list cleaning, and low-volume warm-up; consider switching to a paid SMTP/integration temporarily for critical campaigns.
