Why
Why Are People Switching From Mailshake to Outbound System
Teams move from Mailshake to Outbound System when they need more volume, better targeting, and a team that owns the results.
Built for Volume From Day One
Per-user billing on Mailshake means one connected mail account per user, with one to ten sending addresses depending on plan. Outbound System plans send up to 15,000, 30,000, or 60,000 emails a month across sending infrastructure we set up, warm, and manage, and you never add a seat to send more.
Lists Built For You
Data finder credits on Mailshake run from 50 to 2,500 depending on plan, and your team still runs the searches. Our team builds your prospect list using 10+ intent signals, verifies every contact before launch, and builds new campaigns every month, so Outbound System keeps your list aimed at buyers in market.
Copy Written by Specialists
With Mailshake, an AI writer drafts emails in a minute and your team edits and sends them. Our copywriters have worked on more than 10,400 campaigns. They write each sequence for your buyer and offer, A/B test new angles every week, and keep what books meetings, so Outbound System copy improves every month.
Infrastructure Included
Ready-to-use mailboxes are a Mailshake add-on, and the domains are yours to buy and set up. Outbound System includes domains, inboxes, SPF, DKIM, and DMARC authentication, and warmup in every plan. We host sending on private Microsoft Azure infrastructure with dedicated U.S. IPs, so your team never touches DNS.
A Dedicated Account Manager
Every Outbound System client gets a U.S. account manager, monthly strategy sessions, and a real-time dashboard, not just onboarding. When you want calls too, our AI cold calling makes up to 1,000 dials a day for you, where Mailshake's top plan gives your reps a phone dialer to work themselves.
Deliverability Managed For You
Inbox placement is watched by our team on private Microsoft infrastructure, and average deliverability stays above 98%. Every domain gets SPF, DKIM, and DMARC, sending follows natural patterns, and we rotate inboxes and domains when bounce rates pass 1%, so Outbound System protects your reply rate before it slips.
What Mailshake Costs at Real Volume
Mailshake Starter is $29 per user for 1,500 emails a month. Sending 15,000 at about 30 per inbox a day takes roughly 25 inboxes, while plans include 1, 2, or 10 per seat. That means several $49 to $99 seats, Data Finder at $19 a month, mailboxes, domains, and someone to run it. Outbound System Starter covers it all for $1,499 a month.
Two Good Years, Then Silence
A data company ran cold email in-house for two years with steady leads. Then, over three to four months, replies stopped. Emails were still sending, so the team suspected spam folders but couldn't tell why. Outbound System watches placement and rotates inboxes and domains when bounces pass 1%, before a slow slide becomes a dead quarter.
