Summary
After an accidental email blast and high soft bounce rate, addressing sender reputation requires a multi-faceted approach. Soft bounces signal declining reputation with ISPs, potentially leading to bulk folders or blocks. Immediate actions involve assessing damage, apologizing to recipients, and suppressing problematic contacts. Long-term recovery includes improving list hygiene by removing unengaged users, managing bounces, and segmenting engaged users for targeted sending. Gradually warm up the IP, monitor domain reputation via Google Postmaster Tools and Microsoft SNDS, configure SPF, DKIM, and DMARC for authentication, check blocklists, set up feedback loops, and analyze bounce codes. Ensure permission-based lists and proper segmentation prevent future issues.
