If your emails land in spam, nothing downstream matters — not the copy, not the list, not the offer. Growleady audits your authentication, DNS, blacklist status, and sending patterns, fixes what's broken, and keeps your spam rate under the 0.3% ceiling Google and Yahoo enforce. Audit, remediation, and monitoring included in retainers from $5,000/month.
Email deliverability services are professional services that diagnose and fix why emails land in spam folders instead of inboxes — and keep them landing in inboxes afterward. The work covers four layers: auditing email authentication (SPF, DKIM, and DMARC records and their alignment), checking domains and IPs against blacklists like Spamhaus, measuring spam-complaint rates against the 0.3% ceiling Google and Yahoo have enforced for bulk senders since February 2024, and analyzing sending patterns that trigger filtering. A typical engagement starts with a deliverability audit that produces a ranked fix list, moves through remediation — DNS corrections, blacklist delistings, domain-reputation repair, mailbox warmup — and settles into ongoing monitoring via Google Postmaster Tools and inbox-placement testing. Providers range from independent consultants who audit and advise, to agencies like Growleady that implement the fixes and run the sending infrastructure as part of a broader outbound service.
Four layers of work — audit, infrastructure, remediation, and monitoring — handled by the team that also runs the sending, so advice and implementation never drift apart
A full teardown of why your emails aren’t landing: DNS review covering SPF, DKIM, and DMARC records (syntax, alignment, and policy — not just “does a record exist”), blacklist checks across Spamhaus, Barracuda, and the other lists that actually affect delivery, spam-rate analysis against Google Postmaster Tools data, and inbox-placement testing across Gmail, Outlook, and Yahoo seed accounts. You get a written report of what’s broken, ranked by impact, with the exact DNS changes and sending changes to make.
Sending infrastructure built to protect your primary domain: secondary domains registered for outreach, mailboxes provisioned with SPF, DKIM, and DMARC configured and aligned from day one, and a 2-3 week warmup schedule that builds sender reputation before real volume goes out. We cap sending at 25 emails per mailbox per day and scale volume by adding mailboxes, not by pushing individual addresses past what inbox providers tolerate.
When you’re already in the spam folder: spam-folder recovery, domain-reputation repair, and diagnostics through Google Postmaster Tools and Microsoft SNDS to find what triggered the downgrade. That means identifying the actual cause — a spam-rate spike, a blacklist entry, broken authentication, a burned domain — and either fixing it or making the honest call that a domain is beyond recovery and needs replacing. We tell you which one it is before you spend money on the wrong fix.
Deliverability isn’t a one-time fix — reputation moves with every send. We monitor spam-rate trends in Google Postmaster Tools, watch blacklists for new entries, track bounce rates per mailbox, and run periodic inbox-placement tests, so a problem shows up in a dashboard before it shows up as a dead campaign. When a mailbox starts slipping, it gets pulled, rested, and re-warmed instead of dragging the domain down with it.
An audit is only useful if it's specific. These are the six checks that find the actual cause — not a generic health score.
Not just whether records exist, but whether they work: SPF within the 10-DNS-lookup limit, DKIM keys valid and rotating, DMARC policy set and — critically — aligned with the domain in your From address. Records that exist but don’t align fail authentication just as hard as missing ones.
Duplicate SPF records (which invalidate each other), CNAME conflicts, missing MX records on sending domains, and TXT record typos. These are the boring errors behind a surprising share of “we did everything right” spam-folder cases.
Checks across Spamhaus, Barracuda, SpamCop, SORBS, and the other lists inbox providers actually consult — for both your domains and your sending IPs. Being listed on one that matters can zero out delivery to entire providers overnight.
Since February 2024, Google and Yahoo enforce a hard spam-complaint ceiling of 0.3% for bulk senders — cross it and filtering kicks in regardless of how clean your setup is. We measure your rate in Google Postmaster Tools and work to keep it under 0.1%, because sitting near the ceiling is how one bad campaign takes down a domain.
Link trackers with poor reputations, image-heavy templates, spam-pattern phrasing, and attachment habits that trip content filters. Content matters less than reputation and authentication — but when those are fixed, it’s often the remaining leak.
Volume spikes, burst sending, unwarmed mailboxes pushed to full volume, and bounce rates that signal a stale list. Inbox providers profile how you send as much as what you send; a pattern that looks like a spammer gets filtered like one.
Want a first read before talking to anyone? Run our free deliverability checker, spam checker, blacklist checker, and domain age checker against your own domain. They cover the surface-level checks; the audit goes into the parts a form field can't reach — Postmaster data, sending history, and placement testing.
Five steps from spam folder to stable inbox placement — in the order that actually works
We pull your DNS records, Google Postmaster Tools data, blacklist status, and recent sending history, then run inbox-placement tests to measure where your email actually lands right now. No guessing from symptoms — the audit establishes a measured baseline.
The audit findings get ranked by impact: is this an authentication problem (SPF/DKIM/DMARC failing or misaligned), a reputation problem (spam rate over the ceiling, blacklist entries), a content problem (spam-filter triggers), or a volume problem (sending patterns that look like a spammer)? Most spam-folder cases are two or three of these compounding.
You get a written plan with the specific changes, in order: DNS records to correct, blacklist delistings to request, mailboxes to rest or retire, domains to replace, sending volumes and schedules to change, and content patterns to cut. Each item says what it fixes and roughly how long recovery takes.
We make the changes — DNS updates, mailbox provisioning, warmup schedules, delisting requests — rather than handing you a PDF and wishing you luck. Where reputation has to rebuild, expect 2-4 weeks of disciplined low-volume sending before full volume is safe; anyone promising instant recovery is skipping the part that works.
Once you’re back in the inbox, monitoring keeps you there: spam-rate tracking against the 0.3% ceiling, blacklist watches, bounce-rate alerts per mailbox, and scheduled placement tests. Deliverability decays quietly when nobody owns it — this step is somebody owning it.
An independent email deliverability consultant or expert is the right call when you have a specific, bounded problem and an in-house team to implement the fixes — they audit, diagnose, and hand you a plan, usually billed hourly or per project. The limitation is structural: the consultant leaves, your team makes the changes, and six months later reputation has drifted again with nobody watching the Postmaster dashboard.
An email deliverability agency embeds the same expertise inside an operating service: the people who diagnosed the problem also configure the DNS, provision the mailboxes, run the warmup, and monitor the spam rate week after week — because their own campaign results depend on it. That alignment is the honest argument for the agency model: at Growleady, deliverability isn't a product we sell you and walk away from; it's the foundation our outbound campaigns stand on.
We don't sell deliverability as a separate line item, because separating it from the sending is how it breaks. Every Growleady retainer — from $5,000/month — includes the full deliverability layer: the initial audit, infrastructure setup with SPF, DKIM, and DMARC configured, mailbox warmup, remediation when something slips, and ongoing monitoring. There's no surcharge when a domain needs repair; keeping you in the inbox is already the job.
If you only want a standalone email deliverability audit — you run your own sending and need a specialist diagnosis with a fix plan your team implements — contact us. Scope varies too much with domain count and sending history for an honest flat price, so we'll quote it after a short call rather than publish a number that changes on you.
Everything you need to know about email deliverability services
A complete engagement covers four things. First, an audit: SPF, DKIM, and DMARC validation, DNS review, blacklist checks across lists like Spamhaus and Barracuda, spam-rate analysis in Google Postmaster Tools, and inbox-placement testing. Second, infrastructure: secondary sending domains, properly authenticated mailboxes, and a warmup schedule that builds reputation before volume. Third, remediation when you’re already in trouble: spam-folder recovery, domain-reputation repair, and delisting requests. Fourth, monitoring: spam-rate tracking, blacklist watches, and placement tests so regressions get caught early. Some providers sell only the audit and leave implementation to you — worth clarifying before you buy, because the fix is usually the harder half.
Almost every case comes down to one or more of four causes. Authentication: SPF, DKIM, or DMARC missing, misconfigured, or misaligned, so inbox providers can’t verify you are who you claim to be. Reputation: your spam-complaint rate has crossed the threshold providers tolerate, or your domain or IP is on a blacklist. Sending patterns: unwarmed mailboxes pushed to volume, sudden spikes, or high bounce rates from a stale list — all of which profile like a spammer. Content: spam-trigger phrasing and low-reputation tracking links, though this matters less than the first three. The reason a proper audit comes before any fix is that these compound — patching content while your DMARC is broken fixes nothing.
Under 0.1%, measured in Google Postmaster Tools. Since February 2024, Google and Yahoo enforce a hard requirement for bulk senders: keep spam complaints below 0.3%, or your mail gets filtered regardless of how well-authenticated it is. But 0.3% is the ceiling, not the target — Google’s own guidance is to stay under 0.1%, and senders who hover near the ceiling have no margin for a single bad campaign. In practice that means one spam complaint per thousand delivered emails, which is achievable with tight targeting, verified lists, and honest subject lines, and nearly impossible with scraped lists and bulk blasts.
Typically 2-4 weeks, depending on what’s broken. Pure configuration fixes — correcting SPF records, aligning DMARC — take effect within days of DNS propagation. Reputation damage is slower: inbox providers rebuild trust based on observed sending behavior over time, so a damaged domain needs weeks of disciplined, low-volume, high-engagement sending before full volume is safe. Blacklist delistings range from hours (automated lists) to a week or more (manually reviewed ones). If a domain is badly burned, the honest answer is sometimes that replacement is faster than repair: new domains still need a 2-3 week warmup, but that clock is predictable. Anyone quoting an instant fix is selling you the part that doesn’t work.
Yes — with the caveat that nobody “fixes” Postmaster directly, because it’s a readout, not a setting. Google Postmaster Tools reports your domain reputation, IP reputation, spam rate, and authentication rates as Google measures them. What we fix is the sending behavior those numbers reflect: correcting authentication failures, cutting the list segments generating complaints, pulling volume back under warmup discipline, and rebuilding engagement with tighter targeting. As the underlying signals improve, the Postmaster reputation grade follows — usually visibly within 2-4 weeks. We use the same approach with Microsoft SNDS for Outlook-heavy audiences. Any provider claiming a direct line to reset your Google reputation is describing something that does not exist.
An audit is a point-in-time diagnosis: a structured review of your authentication, DNS, blacklist status, spam rate, and sending patterns, ending in a written report of what’s broken and how to fix it. Consulting is the ongoing relationship: implementing the fixes, making judgment calls as conditions change — when to rest a mailbox, when to retire a domain, how fast to scale volume — and monitoring so new problems get caught early. The audit tells you what’s wrong; consulting keeps it from going wrong again. Most teams need the audit first, and teams running continuous outbound need the ongoing layer, because sender reputation shifts with every campaign.
