Database-bundled sequencer vs. multichannel tool at an accessible price — both losing ground to the new generation.
Autoklose and Mailshake both occupy the mid-tier of cold outreach tooling — accessible pricing, solid fundamentals, and a user base made up largely of SMB sales teams and solo operators. Both have been around long enough to be well-documented but are increasingly competing with tools like Instantly and SmartLead that offer more for less. Understanding what each does well tells you when to consider them over the newer alternatives.
Built-in database vs. multichannel breadth
Autoklose's most distinctive feature is its bundled B2B contact database — you can prospect and sequence from within the same tool without paying for Apollo or a separate data provider. The database quality is decent for SMB targets but does not compete with Apollo's 275M+ contacts or UpLead's verification accuracy. Mailshake does not include a database; it expects you to bring your own contacts. What Mailshake does offer is a multichannel stack — email, cold calling module, and LinkedIn automation — that Autoklose cannot match. If you need data included, Autoklose. If you need multichannel outreach and have contacts already, Mailshake.
Evolution of the product
Mailshake has actively evolved from a pure email tool into a multichannel sequencer with an AI email writer, a built-in cold calling module (ShakerCall), and LinkedIn automation. It has grown closer to the feature set of Salesloft or Outreach at a fraction of the price. Autoklose has remained more focused on its email + data bundling model without the same expansion into multichannel depth. For teams that want the channel breadth without enterprise pricing, Mailshake's current product is the more interesting one.
Pricing and positioning
Autoklose runs $49-99 per user per month with database access included on higher tiers. Mailshake runs $29-99 per user per month depending on which channels you activate. Both are mid-tier in absolute terms. The question is whether you pay more to get data bundled (Autoklose) or pay less for email-only and add data separately, or spend more to get calls and LinkedIn as well (Mailshake).

The verdict
Mailshake if you want multichannel outreach — email, cold calling, and LinkedIn — at a price below what Salesloft or Outreach charge. The evolution of the product makes it more capable than its SMB reputation suggests. Autoklose if you want a built-in B2B contact database bundled with email sequencing and do not want the complexity of managing Apollo or UpLead separately. Both tools are losing market share to Instantly and SmartLead at the email-only end, so the only reason to choose either is for the differentiated features: data bundling (Autoklose) or multichannel breadth (Mailshake).
How does Autoklose's built-in database compare to Apollo or UpLead?
Autoklose's database is functional but smaller and less frequently updated than Apollo's 275M+ contacts or UpLead's 160M+ with real-time verification. For broad ICP searches in common industries, it works. For niche verticals, technical buyers, or international markets, Apollo or UpLead will outperform it. The convenience of not managing a separate data subscription is the main appeal, not data quality superiority.
Is Mailshake's cold calling module worth using?
ShakerCall is a functional power dialer built into Mailshake — it handles click-to-call, voicemail drop, and local presence dialing. It is not as capable as a dedicated tool like Kixie or Orum, but for teams that want one platform for email + calls without a second subscription, it covers the basic use case well.
Should I consider Instantly or SmartLead instead?
For pure email volume at low cost per mailbox, Instantly and SmartLead are stronger tools than either Autoklose or Mailshake. The reason to choose Autoklose or Mailshake is for specific features those tools do not have — built-in data (Autoklose) or native calling + LinkedIn (Mailshake). If you only need email sequences and good deliverability, the newer tools win on price and deliverability tooling.
