Alignedup uses Customer.io for marketing email and SendGrid for transactional/notifications. Email goes out from 2 different subdomains. Their email authentication setup is good (score 80/100).
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 alignedup.com. Policy

SPF alignment: all 52 observed emails use a return-path aligned with alignedup.com (mail.alignedup.com, cio81128.product.alignedup.com, cio81128.alignedup.com). SPF authenticates the visible From — supports DMARC directly.
DKIM alignment: all 43 observed emails sign with a domain aligned with alignedup.com (alignedup.com, cio81128.alignedup.com, cio81128.product.alignedup.com). DKIM authenticates the visible From — supports DMARC directly.

Delivery: fast — 100% of emails in the last 7 days arrive in under 10 seconds (across 11 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.

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 % |
|---|---|---|---|---|---|
| Customer.io | 5 | 80.0% | 20.0% | 0.0% | |
| SendGrid | 48 | 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.
