Warming up
SDRs and AEs depend on cold email delivering to the inbox. One domain deliverability problem doesn't stay isolated — it can affect the reply rates of everyone on the team sending from the same domain.
Most B2B sales teams discover email deliverability the hard way. Sequences go quiet, open rates collapse, and someone in RevOps eventually spots that half the team's outreach is landing in spam. By then, weeks of pipeline are already gone.
Consumer email services (Gmail.com, Outlook.com) have individual reputation. Business email — Google Workspace, Microsoft 365 — shares domain-level reputation across every sender on that domain.
When an SDR sends aggressively from a new mailbox on your company domain and it lands in spam, it's not just their sequence that suffers. The domain's reputation score gets pulled down, and every other sender using that same domain can see inbox placement degrade too. That includes AEs following up on demo requests, CSMs sending onboarding emails, and anyone else using the same @yourcompany.com address.
Warmup, at the sales team level, isn't just about one person's deliverability. It's about protecting a shared sending asset.
Sales teams face a different set of constraints than solo senders or agencies:
The principles are the same regardless of team size, but the order of operations matters.
Warmerly connects to each team member's Gmail or Outlook mailbox via the same OAuth flow they use to connect Outreach, Salesloft, or Apollo. It runs the warmup engine in the background — real peer-to-peer traffic, spam-folder rescue, positive engagement signals — and surfaces the results in a single dashboard your RevOps or sales operations team can monitor.
Because Warmerly is warmup-only, it doesn't touch your sequences, your contact lists, or your CRM data. Your sequence tool and Warmerly use the same Gmail or Microsoft 365 account. There's no routing conflict, no DNS change required, and no interference with existing sending workflows.
Warmerly is priced at $19/month flat per tier — not per mailbox, not per seat. Whether you have 5 SDRs or 25, mailbox warmup costs the same. For sales teams onboarding new hires regularly, that predictability matters.
These patterns come up repeatedly when sales teams start paying attention to deliverability.
Every feature below is available on every plan, including the starting tier.
Warmup all team mailboxes before cold outreach starts. Consistent reputation signals protect the shared domain that everyone — sales, support, leadership — sends from.
Warmerly runs in parallel with Outreach, Salesloft, Apollo, HubSpot Sequences, and other tools. No routing changes, no conflicts. Same Gmail or Outlook account, two separate functions.
Add every SDR and AE mailbox at no extra cost. Warmerly's flat monthly price covers unlimited mailboxes — so onboarding new hires doesn't increase your warmup costs.
SPF, DKIM, DMARC, and MTA-STS are checked every day for every connected mailbox. If your IT team changes DNS records and something breaks, you'll know before it affects outreach.
Seed tests run across Gmail, Outlook.com, Microsoft 365, and other providers. If your prospects use Microsoft 365 and your mail is spam-foldering there, you'll see it before it costs you pipeline.
Every reputation change is logged with a timestamp. When a rep's open rate drops unexpectedly, RevOps can pull up the health timeline and see exactly what changed and when.
Connect a mailbox in 60 seconds. Warmerly starts monitoring immediately and begins the warmup sequence automatically.
Yes. Warmerly connects via standard Google OAuth and Microsoft OAuth — the same authentication methods your sequence tools use. Each team member connects their own mailbox. No admin credentials are shared, and the connection can be revoked at any time from within their Google or Microsoft account settings.
No. Warmerly only runs the warmup engine — it doesn't touch your sequences, contact lists, or sending schedules. Your sequence tool and Warmerly both access the same Gmail or Microsoft 365 mailbox independently. There's no routing conflict.
Especially relevant. Company domains are shared by everyone in the organisation. A deliverability problem on a sending SDR's mailbox can drag down inbox placement for other senders on the same domain. Warming new mailboxes before connecting them to sequences is the single most effective step you can take to protect shared domain reputation.
For a new mailbox on an existing, well-established company domain, 2 to 3 weeks of warmup is typically enough before starting cautious cold outreach. For a brand new company domain (under 60 days old), allow 3 to 4 weeks minimum. Starting too early is the most common cause of early-tenure deliverability problems.
Warmerly is priced at a flat monthly rate — not per mailbox and not per seat. You can connect every SDR and AE mailbox on your team for the same price as connecting one. Check the pricing page for the current plan details.
Yes. Mailboxes can be disconnected from Warmerly at any time from the dashboard. When a rep leaves and their mailbox is closed, disconnect it from Warmerly before or when you deactivate the mailbox. There's no billing impact — your flat monthly rate stays the same.
Agencies don't run one mailbox. They run ten, fifty, or a hundred — across client domains, managed at scale. The economics of warmup look completely different when you're responsible for all of them.
Recruiters live in two channels at once: email to candidates and clients, and LinkedIn to everyone. When the mailbox spam-folders or the LinkedIn account gets throttled, the pipeline stops — and you usually find out a week too late.
