Inbox placement
Also called: Deliverability, Inbox rate, Seed test
Inbox placement is where a delivered email ends up: the inbox, a tab such as Promotions, or the spam folder. Delivery only means the server accepted it.
How it affects cold email
A campaign can have no bounces and still land mostly in spam. Placement is what decides whether anyone reads it, so test it before a big send and after any change to domain, content or tracking.
How Inboxed handles it
- Inbox placement tests send your email to seed mailboxes you add (Gmail, Outlook.com, Yahoo, iCloud, Zoho or others) and check which folder it reaches. Gmail seeds also report the Promotions, Social, Updates and Forums tabs.
- Warmup measures placement continuously too: each mailbox’s health score is the share of its warmup emails that landed in the inbox over 14 days.
