Project description
We run a growing online business and rely on email for order confirmations, password resets and a weekly newsletter, but a painful share of our messages are ending up in the spam folder or getting silently dropped. This started a couple of months ago and it is now costing us real money: customers do not receive receipts, subscribers stop opening, and our sender reputation appears to be sliding. We need an experienced deliverability specialist to diagnose the root cause and put us on a stable footing where mail reliably reaches the inbox at the major providers.
The work covers the full authentication stack. We want SPF reviewed and tightened, DKIM signing set up correctly for every sending source, and a DMARC policy rolled out gradually from monitoring through to enforcement, with aggregate reports interpreted along the way. Beyond DNS records, we expect a proper domain and IP warm-up plan, list hygiene to remove hard bounces, spam traps and stale contacts, and practical fixes to message content, headers and unsubscribe handling that influence placement. Please also check reverse DNS, feedback loops and any existing blocklist entries.
We are comfortable giving access to our DNS zone and sending platform once we agree on scope. Deliverables should be documented so our team can maintain them afterwards, and we would like a clear before/after report using seed tests and provider postmaster data so we can see the improvement in numbers, not just promises.
— Audit current SPF, DKIM, DMARC, rDNS and blocklist status
— Configure authentication for all sending sources and set DMARC to enforcement
— Run a domain/IP warm-up schedule and clean the contact list
— Improve content, headers and unsubscribe for better inbox placement
— Deliver a documented before/after report with seed and postmaster metrics
