Wix Forms uses Wix for marketing email and SendGrid for transactional/notifications. Their email authentication setup is good (score 65/100). 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 2 emails we've observed. DMARC policy is read live from DNS.
SPF alignment: observed emails use a third-party return-path (tece-sta.co.jp) — SPF passes there but doesn't align with wix-forms.com, so DMARC has to rely on DKIM alignment.
DKIM alignment: all 104 observed emails sign with a domain aligned with wix-forms.com (wix-forms.com). DKIM authenticates the visible From — supports DMARC directly.
TLS: modern — 100% TLS 1.3 (across 7 sends).
Delivery: fast — 100% of emails in the last 7 days arrive in under 10 seconds (across 2 sends).
Brands often use multiple ESPs (e.g. one for marketing, another for transactional/notifications).
None — only the primary ESP(s) shown aboveESPs 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.
No SPF record published on the apex wix-forms.com. Emails from this brand still pass SPF — most ESPs handle SPF on a sending subdomain (Return-Path) rather than the apex. Adding an apex SPF (even v=spf1 -all) would block direct spoofing of unused From: addresses.

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 | 56 | 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 % |
|---|---|---|---|---|---|
| SendGrid | 40 | 100.0% | 0.0% | 0.0% | |
| Wix | 15 | 100.0% | 0.0% | 0.0% |
Daily observations per ESP. Brands often run multiple ESPs concurrently — marketing on one, transactional on another — so this chart shows usage rather than switches.
