ChkIP (formerly IP Mailer) Pricing, Pros, and Cons Compared

Top 7 Tips for Optimizing Campaigns with ChkIP (formerly IP Mailer)

1. Verify and warm new IPs

• Why: New or unused IPs have no reputation; sending high volume immediately risks blocks.
• How: Start with low-volume, high-engagement sends; gradually increase volume over 2–4 weeks while monitoring bounce and complaint rates.

2. Maintain a clean, segmented list

• Why: Higher engagement and lower bounces improve deliverability and sender reputation.
• How: Remove hard bounces, suppress inactive addresses (e.g., no opens in 6–12 months), and segment by recency and engagement for targeted content.

3. Authenticate emails properly

• Why: Proper authentication (SPF, DKIM, DMARC) reduces spoofing risk and improves inbox placement.
• How: Ensure SPF records include ChkIP’s sending hosts, publish DKIM keys ChkIP provides, and implement a DMARC policy aligned with your goals (p=none/quarantine/reject).

4. Optimize content for engagement and filtering

• Why: Spam filters and provider algorithms favor content that drives opens and clicks and avoids spam signals.
• How: Use clear subject lines, personalized preheaders, concise copy, balanced image-to-text ratio, and avoid spammy words/too many links. Include a visible unsubscribe link and proper List-Unsubscribe headers.

5. Monitor deliverability metrics and feedback loops

• Why: Timely detection of deliverability issues enables fast corrective action.
• How: Track opens, clicks, bounces, complaint rate, and inbox placement. Enroll in ISP feedback loops where available and immediately suppress complaining addresses.

6. Use dedicated IPs when appropriate

• Why: Dedicated IPs give you control over reputation when sending consistent volume.
• How: Choose dedicated IPs once you have steady sending volume; continue IP warming and keep consistent sending patterns. For low-volume senders, use shared IP pools managed by ChkIP to benefit from established reputation.

7. A/B test and iterate on cadence and creative

• Why: Continuous testing finds the best subject lines, send times, frequency, and content mix for your audience.
• How: Run controlled A/B tests (subject line, send time, CTAs), measure statistically significant differences, and roll out winners. Adjust sending cadence to balance engagement and fatigue.

Bonus quick checklist

• Confirm SPF/DKIM/DMARC
• Warm IPs slowly
• Segment by engagement
• Suppress bounces/complaints
• Monitor metrics daily/weekly
• Test subject lines and send times
