Reply Rate Tanked? A 6-Step Deliverability Triage
Don't rewrite copy first. Diagnose placement in this order.
— Step 1: send a seed test through GlockApps or MailReach. Inbox vs spam vs Promotions, per provider.
— Step 2: check domain/IP on MXToolbox blacklists. Spamhaus and Barracuda first.
— Step 3: verify SPF, DKIM, DMARC still pass — DNS changes silently break these.
— Step 4: pull your bounce rate. Above 3%? Your list is dirty; re-verify with ZeroBounce or NeverBounce.
— Step 5: audit send volume per mailbox. Over 50/day on Google Workspace is asking for it.
— Step 6: only now, review copy for spam-trigger words and link count.
Pros
— Finds the real cause instead of guessing
— Most fixes are infra, not copy
Cons
— Seed tests cost money per run
— Blacklist delisting can take days
Verdict: Infrastructure before wording, every time. 4.5/5.
Who it's for: Anyone watching replies drop with copy they know used to work.
