Smashburger uses Braze as their primary email service provider. They rank #150,166 in the Tranco list of most-popular domains. Email goes out from 2 different subdomains. Their email authentication setup is solid (score 95/100).
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.
DMARC enforced with p=reject — receivers actively reject or quarantine spoofed mail. No aggregate reporting destination configured.
DKIM alignment: 50% of observed emails sign with an aligned DKIM key (e.smashburger.com); the rest sign with third-party keys (mailgun.org) where DMARC has to rely on SPF alignment.
1 of 2 emails in the last 7 days were delayed beyond 5 minutes (50%) — peaks past 15 minutes are well outside healthy sender behaviour. Slow sends averaged 56 min. Healthy senders deliver in under 30 seconds. Consistent delays usually mean greylisting, reputation-based throttling, or receiver-side filter scrutiny — worth investigating sender reputation and authentication setup.
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.
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 |
|---|---|---|
| promotions | 1 | 33.3% |
| spam | 2 | 66.7% |
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 % |

| Braze | 3 | 0.0% | 33.3% | 66.7% |
Daily observations per ESP. Brands often run multiple ESPs concurrently — marketing on one, transactional on another — so this chart shows usage rather than switches.
