Technical Excellence Matters
Setting up SPF, DKIM, and DMARC isn't optional - it's essential. We guide you through every step to authenticate your domain and build sender reputation. Whether you're sending transactional emails or marketing campaigns, authentication ensures they reach the inbox.
| Deliverability layer | What it proves | What to monitor |
|---|---|---|
| SPF | Your sending servers are authorized | DNS record validity |
| DKIM | Your message was not modified | Signature pass rate |
| DMARC | Your domain has an enforcement policy | Alignment and policy failures |
| Bounce handling | Bad addresses are removed | Hard bounce rate |
| Complaint handling | Spam complaints are processed | Complaint rate |
Protect Your List Health
Automatic bounce handling removes hard bounces before they hurt your sender reputation. Combined with list management tools, you maintain a healthy list that actually engages with your emails.
| List health signal | Healthy range to watch | Action if it worsens |
|---|---|---|
| Hard bounce rate | Under 0.5-1% | Remove invalid addresses |
| Spam complaint rate | Under 0.1% | Review consent and frequency |
| Unsubscribe spike | Campaign-dependent | Check message relevance |
| Low engagement | Segment-specific | Re-engage or suppress |
| Authentication failure | Should be near zero | Fix DNS before sending more |
Every Email Feature Depends on Deliverability
