Tdsynnex uses HubSpot as their primary email service provider. They rank #35,876 in the Tranco list of most-popular domains. Their email authentication setup is solid (score 85/100).
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 10 emails we've observed. DMARC policy is read live from DNS.
DMARC reports sent to tdsynnex.com. Policy
p=reject means receivers actively block or quarantine spoofed mail.
SPF alignment: observed emails use a third-party return-path (bf53x.hubspotemail.net) — SPF passes there but doesn't align with tdsynnex.com, so DMARC has to rely on DKIM alignment.
DKIM alignment: all 55 observed emails sign with a domain aligned with tdsynnex.com (tdsynnex.com). DKIM authenticates the visible From — supports DMARC directly.
TLS: 0% TLS 1.3, 100% TLS 1.2 (across 35 sends).
Delivery: fast — 100% of emails in the last 7 days arrive in under 10 seconds (across 14 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.
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 | 55 | 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 % |

Daily observations per ESP. Brands often run multiple ESPs concurrently — marketing on one, transactional on another — so this chart shows usage rather than switches.
