Their email authentication setup is good (score 73/100). Missing: DMARC enforcement. We've recorded 4 ESP changes since first observing this brand.
Authentication signals observed in this brand's emails. SPF, DKIM and DMARC are the standard sender-authentication stack — see the DMARC policy below for whether spoofing is actually blocked or just monitored. One-click unsubscribe meets Google & Yahoo's bulk-sender requirements.
SPF / DKIM / DMARC above reflect the last 10 emails we've observed. DMARC policy is read live from DNS.
DMARC published as p=none with no rua= reporting — monitor-only, and the sender isn't collecting reports either.
SPF alignment: all 39 observed emails use a return-path aligned with portolapaints.com (k3.send.portolapaints.com, mailer7qb.portolapaints.com, mailer006.portolapaints.com). SPF authenticates the visible From — supports DMARC directly.
DKIM alignment: all 34 observed emails sign with a domain aligned with portolapaints.com (send.portolapaints.com, mailer7qb.portolapaints.com, portolapaints.com). DKIM authenticates the visible From — supports DMARC directly.
TLS: 75% TLS 1.3, 25% TLS 1.2 (across 28 sends).
Delivery: fast — 100% of emails in the last 7 days arrive in under 10 seconds (across 16 sends).
Brands often use multiple ESPs (e.g. one for marketing, another for transactional/notifications).
Shopify Messaging 9ESPs we've seen sending email for this brand. Green = confirmed by SPF, sender IP rDNS, or known infra pairing (label shows the source). Grey = observed but not yet confirmed by SPF or PTR.
ESPs this brand has authorized in their SPF record. We confirm them with a green ✓ only after seeing recurring use (3+ emails across 2+ days). Until then they stay here — either we haven't observed any email yet, or we've seen a handful but not enough to call them a regular sender for the brand.

Folder distribution across all emails from this brand observed in Gmail inboxes. High inbox % = good deliverability; spam appearances are the headline signal.
| Folder | Count | Share |
|---|---|---|
| inbox | 38 | 100.0% |
Which ESP's emails are landing where. Sorted by spam % so problem senders surface first. Brands using one ESP for marketing and another for transactional often see very different placement profiles per ESP. Per-ESP folder data only started being captured recently — counts here may be smaller than the total above until backfill catches up.
| ESP | Emails | Placement | Inbox % | Tabs % | Spam % |
|---|---|---|---|---|---|
| Klaviyo | 28 | 100.0% | 0.0% | 0.0% | |
| Shopify Messaging | 9 | 100.0% | 0.0% | 0.0% |
