Outbound Tip of the Day: Instead of using an “Unsubscribe” button, spintax a few random key words for prospects to say if they want to opt out, example: “If you’re not interested say ‘{bird|fruit|peanut}’ and I’ll stop emailing you”
Your Emails Are Probably Landing In Spam…
I’ve had multiple consultations with prospects over the last few weeks about their email infrastructure.
Even in 2025, 97% of teams have deliverability COMPLETELY wrong.
Sending 100+ emails/day/inbox, sequencing emails from Hubspot or Apollo, neglecting email warm-up, tracking open rates, etc.
Poor deliverability infrastructure is actively cutting their outbound sales revenue potential by 70%+.
So here’s a breakdown of the deliverability setup & protocols we use for 98% deliverability across millions of email sends for our B2B clients:
1/ Deliverability Tool Stack
Email sequencing: EmailBison(.)com
> Isolated IP email sending
> Premium warm-up pool
> Catered for teams looking to send 100k+ emails/month.
Email inboxes: ScaledMail(.)com
> Premium inboxes reseller
> 24-48 hour turn around time
> Great pricing for scale
> Top notch team, they know deliverability better than 99.9% of the market
2/ Email Inbox Setup + Allotment
Inbox / Domain Ratio:
> Google: 2 inboxes / 1 domain
> Microsoft Azure: 25 inboxes / 1 domain
ESP Providers:
> Google (80%)
> Microsoft Azure (20%)
[Note on ESP ratio]: as of Q4 2025, we are currently leveraging more in Google at the moment due to consistently seeing Google inboxes outperforming Outlook by margins of 2X+ at times. This is subject to change as time goes on.
Inbox Rotation + Reserve Ratio:
> Monthly Rotating Email Batch 1 (40% of total inboxes)
> Monthly Rotating Email Batch 2 (40% of total inboxes)
> Reserve Email Batch (20% of total inboxes)
[Note on rotation & reserve]: Batch 1 & 2 will swap out of campaigns month over month, each sending in 30 day intervals at most. Reserved email batch serves as insurance for ESP black swan events where infrastructure gets wiped or compromised.
3/ Email Sending Protocols
Email Warm-up
> Volume (Google): 30 warm emails/day
> Volume (Microsoft): 10 warm emails/day
> Reply rate (G & MS): 65%
> 2 weeks warm-up before cold sending minimum
> Warm-up remains on at all times
> 1/2 cold/warm email sending ratio (ex. 15 cold, 30 warm)
Email Ramp-up
> Google volume increase (Safe): 1 email/inbox/day
> Google volume increase (Aggressive): 3 emails/inbox/day
> Microsoft volume increase (Safe): 1 email/inbox/7 days
> Microsoft volume increase (Aggressive): 1 email/inbox/2-3 days
Email Cold Sending Volume:
> Google: 15 emails/day/inbox
> Microsoft: 5 emails/day/inbox
Email Campaign Deliverability Settings:
> Open tracking: OFF
> Plain text emails: ON
> New Contact/Follow-up Sending Ratio: 80%/20%
> Email scripts cleared of spam words
> Heavy spintax / Multiple script variants
This is the full deliverability playbook, all you need to do to achieve 98%+ deliverability consistently. Just follow this step-by-step and you’ll be golden.
