Email deliverability for ecommerce brands.
Email deliverability is whether your emails reach the inbox rather than the spam folder or the promotions tab. Inferno Emails fixes it for ecommerce brands by configuring SPF, DKIM and DMARC, repairing sender reputation, cleaning the list and monitoring inbox placement.
Deliverability is the least glamorous part of email and the one that quietly decides whether any of the rest of it matters. If Gmail has decided you are promotional noise, your best campaign of the year lands in a tab nobody opens. We fix the technical foundation first, then keep it clean.

What we take care of.
The best offer in the world earns nothing from the spam folder. Authentication, reputation and list hygiene, handled.
- SPF, DKIM and DMARC configured and verified
- Dedicated or shared sending decision, made on your actual volume
- Sender reputation diagnosis and warm-up plan where needed
- List hygiene: suppression of hard bounces, spam traps and long-dead contacts
- Sunset and re-engagement flows so dead weight stops dragging you down
- Ongoing inbox placement and complaint-rate monitoring
Emails that reach the inbox, so campaign performance reflects the offer rather than the filter.
How we approach it.
We check authentication first: SPF, DKIM and DMARC on the domain you actually send from. Most delivery problems that are not list-related start here.
Next we look at list health: how much of the list has not engaged in six months, how bounces and complaints are trending and whether inactive contacts are dragging reputation down.
Fixes are staged. We clean and segment, smooth out sending volume, and warm up carefully, then monitor placement so the improvement shows up in revenue, not just in a report.
Is this the right fit?
Who this is for
- Open rates have drifted down and nobody can say why
- Mail is landing in spam or the Promotions tab at Gmail or Outlook
- You have never checked SPF, DKIM and DMARC, or are unsure they are correct
Who this is not for
- You bought or scraped your list and plan to keep mailing it
- You are not willing to stop sending to long-inactive contacts
- You expect a fix without any change to how you send
The first 30 days.
- Week 1We are in your account. Audit, authentication check, and a list of what to fix first, in order.
- Weeks 2 to 3Core flows go live and the first campaigns send, designed in your brand and approved by you.
- Week 4First monthly report against attributed revenue, and the test plan for the month ahead.
What we need from you
- Read-only access to Klaviyo and your store platform, or screenshots if you prefer
- Brand assets: logo, fonts, colours and product photography
- One person who can approve copy and offers within a couple of working days
What we fix most often.
- Mailing the full list at full volume after a long gap, which spikes complaints
- Publishing a DMARC record at p=none and never moving beyond it
- Ignoring the share of the list that has not opened in six months

Questions about email deliverability.
How do I know if I have a deliverability problem?
The usual signs are open rates falling steadily over months, a widening gap between delivered and opened, complaint rates above 0.1%, or revenue dropping while send volume stays flat. Our free audit checks your authentication records and flags these.
How long does it take to fix a damaged sender reputation?
Authentication problems are fixed in days. Reputation repair is slower: typically four to eight weeks of disciplined sending to engaged segments while the damaged history ages out. Anyone promising a fix in a week is guessing.
Will cleaning my list hurt my revenue?
Suppressing unengaged contacts almost always raises revenue, not lowers it. Those contacts were not buying; they were dragging your reputation down and taking the engaged ones with them into the promotions tab.
How much does deliverability repair cost?
It depends on how much repair the account needs, from an authentication fix that takes days to a full reputation rebuild that typically takes four to eight weeks, so we quote after the free audit rather than a flat fee. The audit itself is free and has no obligation attached.
What access do you need to fix deliverability?
Read-only access to your Klaviyo account is fastest, since we need to see your authentication records, complaint rates and list health before changing anything. If you would rather not grant access, screenshots of those same three things get us most of the way there.
