How Physis Mail Enhances Email Deliverability in 2026

7 Tips to Optimize Your Campaigns with Physis Mail

1. Segment your list by behavior and value

  • Create segments for recent opens/clicks, purchase history, and high-LTV customers.
  • Send tailored messaging and offers per segment.

2. Personalize beyond name

  • Use behavioral fields (last product viewed, location, preferred category).
  • Insert dynamic content blocks for relevant offers.

3. Optimize subject lines & preheader

  • A/B test 2–3 variants (benefit, curiosity, urgency).
  • Keep preheader complementary and mobile-friendly (35–50 chars).

4. Send-time optimization

  • Use per-recipient send-time if available; otherwise test best days/times and apply by segment.
  • Reduce frequency for low-engagement segments.

5. Clean and warm your list

  • Remove hard bounces and inactive addresses after a re-engagement flow.
  • Use gradual warm-up for new sending domains/IPs to protect deliverability.

6. Design for mobile and accessibility

  • Single-column layout, 1–2 CTAs, buttons at thumb height.
  • Use semantic HTML, alt text for images, 14px+ readable fonts and sufficient contrast.

7. Track, test, and iterate

  • Measure opens, clicks, CTR, conversion rate, unsubscribe and deliverability.
  • Run structured A/B tests (subject, CTA, layout) and roll out winners; keep a testing calendar.

If you want, I can turn these into a 4-week optimization checklist or provide subject-line and preheader examples tailored to your audience.
