QuickMail is the cold email tool that outbound agencies keep coming back to. Built-in warmup, unlimited inboxes, client dashboards, and inbox-level deliverability analytics make it a strong choice for teams managing cold email for multiple clients.
QuickMail is a strong 4.3/5 pick for agencies - because the Auto Warmer is built in. It operates its own warmup network of 30,000+ inboxes, so you skip the $29-49/month external warmup that tools like Mailshake require. Unlimited inboxes on the $89/mo Pro plan keeps multi-client management cheap. The trade-offs: no built-in email verification and higher per-seat cost as you add users - verify your list with BounceZero before your first send.
QuickMail operates its own warmup network of 30,000+ inboxes. Auto Warmer sends positive signals to new inboxes without requiring a subscription to a third-party warmup tool. This saves $29-49/month compared to Mailshake users who need external warmup.
The $89/month Pro plan includes unlimited sending inboxes. For agencies running 5-50 client inboxes, this is dramatically cheaper than Mailshake ($58/user/inbox) and more flexible than Instantly (which charges per seat).
QuickMail shows open rates, reply rates, bounce rates, and spam rates per inbox - not just per campaign. This makes it easy to identify underperforming inboxes before they damage a client domain.
QuickMail maintains a shared block list across all users. When any QuickMail user marks a domain as unsubscribed or reports a bounce, all QuickMail users are protected from sending to that contact. Reduces global bounce rates.
Weekly automated reports per inbox showing warmup status, spam placement, and deliverability score. Agencies can share these directly with clients without building custom reports.
Connect any SMTP provider (Gmail, Outlook, any custom SMTP) or use the QuickMail API to trigger sends from your CRM. Broad compatibility compared to tools that require OAuth-only connections.
QuickMail is email-only. No LinkedIn connection requests, profile views, or message steps. For multichannel sequences, pair QuickMail with a dedicated LinkedIn tool or switch to Mailshake or Lemlist.
The AI email generation is a simple template filler, not a full personalisation engine. Teams doing hyper-personalised outreach (custom first lines per contact) will need external AI tools.
QuickMail connects to CRMs via Zapier or API only - no native Salesforce or HubSpot integration. This adds setup time and requires a Zapier subscription for many teams.
QuickMail UI has not had a major redesign in several years. It works but feels less polished than Instantly or Smartlead. New users face a steeper learning curve than with more modern interfaces.
