The best time to send, by when brands actually send

This is when brands send most, not proof those times perform best. Sunday is the busiest day (23% of sends) and Friday the quietest (9%). 12pm is the most common hour to send (26%). Times are US Eastern. The typical brand sends 4.2 campaigns a week, across 19 brands with a long enough run of mail to judge. Each of the 21 brands counts equally, whatever its volume, across 510 scheduled campaigns; welcome, cart and order emails are left out, because they go out when a subscriber acts rather than when the brand chooses to send.

Which domain the mail actually comes from

Deliverability guides tell brands to send marketing from a dedicated subdomain rather than their root domain. In practice, 14% of brands do. The most popular labels are eml., mail. and email., tied at 33% of subdomain senders each. Measured across 21 brands with a known website; a brand can appear under more than one style when it sends from several domains.

Which network actually delivers the mail

The platform a brand logs into is not always the one whose servers hand the mail over. Reading each campaign's Received headers, 67% of campaigns left from SendGrid's network. Klaviyo mail left from SendGrid (65%) and Amazon Web Services (35%). 65% of campaigns came from a server named after the brand rather than its provider. Measured across 544 campaigns from 21 brands; the network is whoever announces the sending IP's route.

Whose name is on the sending server

The brand's like mta4.e.westelm.com 65% of campaigns
The provider's like o1377.shared.klaviyomail.com 35% of campaigns

11 brands (52%) sent at least one campaign from a server carrying their own domain, usually a sign of dedicated IPs.

A cloud network (AWS, Azure, Google Cloud) means the platform runs its own mail servers on rented machines.

How brands handle unsubscribes

100% of campaigns carry a List-Unsubscribe header, the one that lets Gmail, Apple Mail and Yahoo show an unsubscribe button next to the sender's name; 0% (0 campaigns) go out without one. 100% support one-click unsubscribe (RFC 8058), which Gmail and Yahoo have required of bulk senders since 2024.

Every figure here is counted from emails you can open, read as text, and inspect header by header.

How this is measured

Every figure comes from real emails captured in Inbox Archive, not surveys. Send times come from each message's Date header, converted to US Eastern, with each brand weighted equally; welcome, cart and order emails are left out of them. Subject-line words are counted across every subject, leaving out common words and brand names. Cadence is each brand's campaigns per week over the span it has been archived, for brands with at least three campaigns over two weeks.

The ESP is detected from message headers and sending infrastructure; tracking and personalization tech from asset and click domains in the HTML; campaign type and promo codes from the email content. Sending domains come from each campaign's From address, compared against the brand's own website. Unsubscribe figures read the List-Unsubscribe headers as each message arrived. Sending networks come from the outbound IP in the Received headers, attributed to the network that announces its route (via Team Cymru's IP-to-ASN service).

Figures cover 544 published campaigns from 21 brands sent between Jul 2026 and Oct 2026. A section only appears once it covers at least 10 brands and 50 campaigns. Browse the data by provider, tracking tech, or campaign type.
