About

MyColdInbox is a web-based shared inbox and email management platform for teams handling cold-outreach replies across multiple sending accounts. It connects Gmail and Google Workspace, Outlook and Microsoft 365, and compatible IMAP/SMTP mailboxes, bringing incoming messages into a unified workspace with each message linked to its source mailbox. Teams can filter and search conversations, label replies, assign threads to teammates, add internal notes, and reply from the original sending account. Role-based workspaces support agencies managing client inboxes, as well as sales development, lead-generation, recruiting, and founder-led outreach teams. MyColdInbox manages replies rather than sending campaigns, allowing teams to keep using their existing campaign tools. It also includes thread status tracking and shared or personal inbox visibility settings.

About

PureMail provides managed Google Workspace and Microsoft 365 email inboxes for teams running cold-email outreach. Customers supply their own domains and select an inbox volume; PureMail provisions mailboxes, configures SPF, DKIM, DMARC and MX records, and connects accounts to sending platforms such as Instantly, Smartlead, Lemlist and other sequencers. Plans are billed monthly per inbox, with volume-based rates, DNS setup and integration included and no setup fee. Accounts include mobile and web access, while support is available through dashboard tickets. PureMail is intended for lead-generation agencies, B2B sales teams, SDRs, founders and other outbound teams that need multiple business email inboxes. The company also publishes a cold-email tool directory with provider pricing, sending limits and rubric scores.

Pros & Cons from Real Users

Pros

  • 24/7 support responds within minutes not hours. Pinged at 2am about a pre launch issue and had a working solution before i went back to sleep. Real availability not marketing 24/7 like some vendors.
  • Lead gen campaigns depend on infrastructure running without interruption. Puremail inbox stability lets us focus on message and targeting instead of firefighting sending issues mid campaign.
  • Puremail account deliverability tested measurably higher than other providers using identical content across sends. Real difference showed up in inbox placement and downstream reply rates.
  • Dashboard handles hundreds of inboxes without becoming unusable. Bulk filtering, selection, actions all work well. Enables one person to manage what would otherwise need dedicated ops headcount.
  • Powers cold email infrastructure across 15+ client accounts for our agency. Reliable batches, consistent quality, and the setup handling saves us hours per new client onboarding process.

Cons

  • Public status page for provisioning reliability would be nice.
  • Campaign level pause and resume across all inboxes for one client would help.
  • Per inbox deliverability metrics inside the dashboard would help ops.
  • Bulk actions on 500+ inbox selections could be a bit faster.
  • Agency workspace view for multiple client account groups would be a great addition.
