Real teams, real inbox placement

Mangools

SEO toolkit

Facing a 3-million-email Black Friday send on a cold IP, Mangools warmed new IPs and turned a spam problem into a record campaign.

Wishpond

Marketing automation

Wishpond’s marketing emails were missing the inbox. After adding Warmup Inbox, deliverability climbed and warming every new mailbox became standard practice.

SellersCommerce

B2B ecommerce

SellersCommerce’s emails were stuck in spam. Warming three mailboxes and using Warmup Inbox’s deliverability tools pushed placement to 95% and doubled opens.

Leadspicker

Sales automation

Rather than build warmup in-house, Leadspicker integrated Warmup Inbox into its platform, saving roughly two years of development.

i-batu

B2B SaaS · Spain

i-batu’s client campaigns were landing in spam. Warming their mailboxes lifted open and response rates and started generating qualified leads.

Italian Artisan

Luxury manufacturing

Connecting global fashion brands with 800+ Italian workshops, Italian Artisan uses Warmup Inbox to protect deliverability and win high-profile clients.

Avvy’s cold outreach deliverability had collapsed to 60–70%. A disciplined warmup routine brought it back above 90% and keeps it there.

Aerosend benchmarks warmup tools for the clients it helps send nearly 50 million cold emails. After testing more than six providers, it scaled on Warmup Inbox.
