What to compare before switching
- who supplies the mailboxes and domains, and who owns their reputation;
- whether billing follows users, contacts, monthly volume, or actual emails;
- whether lead data, enrichment, CRM, LinkedIn, or calling is required;
- whether the team needs a unified inbox, reply handling, API, or client workspaces;
- whether the provider policy permits the contact source and traffic type.
1. Bulko
Bulko is the narrowest option in this list. It supplies configured pre-warmed SMTP accounts, list checks, content variation, delivery statistics, reply collection and classification, and API access. Credits do not expire. It does not include a prospect database, full CRM, client workspaces, LinkedIn automation, or ownership of the sending mailboxes.
2. Smartlead
Smartlead is designed for ongoing outbound operations with many mailboxes. Base starts at $39 per month for 6,000 sends; higher plans add much more volume, CRM access, verified prospects, premium warm-up and agency-oriented options. It is a strong choice for operational scale, but private infrastructure and client workspaces can depend on plan or add-ons.
3. Lemlist
Lemlist's Email plan starts at $69 per month for 50,000 emails and supports unlimited users and senders. The $109-per-user Multichannel plan adds LinkedIn actions and calling. Lemlist is the strongest option here when visual personalization and coordinated channels matter, but it is broader and more expensive than a focused sending service.
4. Mailshake
Mailshake Starter costs $29 per month with 1,500 sends. Email Outreach costs $49 and adds unlimited sends, two email addresses, rotation, a unified inbox and CRM integrations; Sales Engagement adds calling. Mailshake fits teams that want a familiar sales-engagement workflow, but ready-to-use mailboxes are a separate paid product.
5. Apollo
Apollo is data-first: its platform combines a B2B database, enrichment, intent, sequences, CRM integrations and pipeline tools. The Free plan has 900 annual credits; Basic is $49 per user per month with annual billing and 30,000 annual credits. Apollo is compelling when finding contacts is part of the purchase, but its data credits are not email-send credits.
Choose by use case
- Pay only for sending: Bulko;
- Operate many mailboxes: Smartlead or Instantly;
- Multichannel: Lemlist;
- Traditional sales engagement: Mailshake;
- Contact discovery and enrichment: Apollo;
- Controlled cold-email automation: Woodpecker.
Verdict
The best alternative is defined by the capability or billing model missing from the current product. For a direct comparison with Bulko, read Instantly vs Bulko.
If managed SMTP without a subscription fits the requirement, review Bulko email packs or test 500 credits.
