Only 4.4% of emails reach the primary inbox, which is significantly below the ideal benchmark of 99%, highlighting a major challenge for ecommerce brands aiming for direct inbox engagement.
The spam rate remains relatively low at 3.5%, indicating good compliance with email sending standards. Industry variations exist, with some niches performing slightly better or worse in inbox placement, though the Promotions folder dominance remains consistent. The Health & Supplement industry has the highest spam rate at 20.53%, while the Fashion & Apparel sector shows the lowest at 0%.

Analyzing email deliverability data across 9 industries reveals a significant relationship between domain authentication (SPF, DKIM, DMARC) and inbox placement rates. Industries with higher authentication rates show better inbox placement and reduced spam rates.
The Fashion & Apparel Industry has a low inbox rate at 0.07%, with SPF at 99.68%, DKIM at 99.22%, and DMARC at 96.50%. Despite high authentication, this industry struggles with inbox placement, likely due to other factors like email warm-up or email volume.

Beauty & Cosmetics Industry, on the other hand, has near-perfect authentication (SPF: 99.71%, DKIM: 100%, DMARC: 99.07%) but still suffers from an inbox rate of 0.00%. The high promotion rate (94.48%) and low spam rate (5.52%) show that while authenticated emails are less likely to be marked as spam, the content might need improvement to engage recipients effectively.
Brands implementing full domain authentication protocols (SPF, DKIM, DMARC) and a dedicated IP address still see improved deliverability outcomes, underscoring the importance of these technical practices.

We analyzed more than 4500 emails from 850+ ecommerce brands that landed in the SPAM folder of several inboxes in Q1 2025. These emails include e-commerce brands from across the e-commerce industry, including and beyond the 9 e-commerce industries discussed above.
Here’s what we found from our analysis of SPAM emails, their sending domains, and IP addresses.
In our analysis, 47.64% of SPAM emails were sent from shared IP addresses. This indicates that nearly half of the SPAM emails in our sample were associated with shared IPs. If other brands using the same shared IP have poor sending practices, it can negatively affect the deliverability for all users sharing that IP.
The data reveals that shared IPs are less likely to be flagged as spam in isolation. However, the primary concern lies in the broader impact on email deliverability when the IP’s reputation is compromised. Non-shared IPs, while exhibiting a slightly higher spam rate, provide more control over reputation management, allowing brands to safeguard their deliverability by following the best practices.
Shared IPs, while not the sole factor in spam delivery, contribute significantly to deliverability issues. A shared IP’s reputation can be compromised by the actions of other senders, leading to broader risks of blacklisting and higher spam placement rates. Additionally, it’s crucial to monitor IP reputation regularly, especially when using shared IPs, to ensure your email campaign deliverability is not affected.
We further segmented and analyzed 1,199 emails sent from non-shared IP addresses. We found that even with a solid IP reputation and domain authentication, subject line keywords could be another reason to trigger spam filters. Our analysis revealed that words like “sale” (63 occurrences), “free” (35 occurrences), and “offer” (12 occurrences) are frequently used in subject lines, making them prime candidates for being flagged as spam. While a good IP reputation and proper authentication are important, avoiding these aggressive promotional keywords in your subject lines can significantly reduce the risk of landing in the spam folder and improve deliverability.
Our comprehensive study across nine industries reveals high adoption rates of these protocols, with average compliance at approximately 97% for SPF, 96% for DKIM, and 95% for DMARC. This near-universal implementation underscores the critical importance brands place on securing their email streams.
SPF (Sender Policy Framework): Verifies that sending mail servers are authorized to send email on behalf of your domain.
DKIM (DomainKeys Identified Mail): Adds a digital signature to verify email hasn’t been tampered with in transit.
DMARC (Domain-based Message Authentication): Tells receiving servers how to handle emails that fail authentication checks.
Begin sending low volumes of emails and steadily increase volume to build positive engagement without triggering spam filters.
Send to your most engaged subscribers early on to ensure high open and click rates, which boosts your sender reputation.
Track deliverability metrics and recipient behavior closely, adjusting sending patterns to maintain IP health and avoid blocks.
Email warm-up is a crucial process that helps new or inactive IP addresses establish a positive sending reputation with Internet Service Providers (ISPs) and Email Service Providers (ESPs). Gradually increasing sending volume signals to ESPs that your emails are legitimate and welcomed by recipients. A strong IP reputation minimizes the risk of emails landing in spam folders or being blocked outright, ensuring higher inbox placement and better engagement. Maintaining this trust through consistent, quality sending practices safeguards your brand’s deliverability over time.
