MailerSpark review
A combined newsletter and outreach tool, with sending routed through your SMTP or Amazon SES.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
MailerSpark brings newsletter campaigns and cold outreach sequences into one cloud platform for newsletter operators, sales teams, agencies, and developers. It also includes a contact CRM, audience segments, visual automation workflows, campaign tracking, and a unified inbox for replies. That breadth can suit small teams seeking an alternative to Mailchimp that also handles outreach, while teams focused only on newsletters may not need the added sequence and inbox features.
Sending depends on a customer-connected SMTP provider or Amazon SES. The listed integrations include Amazon SES, Gmail, Microsoft 365, SMTP, Ollama, and OpenAI; the platform also offers a REST API and signed webhooks. Newsletter operators can schedule campaigns and track opens, clicks, and revenue, while outreach sequences support wait steps and stop-on-reply. This combination gives the product a clear campaign-and-outreach focus, though teams reliant on a broader set of named integrations may find the ecosystem fit narrow.
The Free plan costs $0 per month and includes newsletter campaigns, contact CRM, a drag-and-drop builder, and BYO SMTP and Amazon SES. The published description specifies up to 500 contacts and 1,000 emails per month. Starter is $19 monthly and adds automations (Beta), A/B subject line testing, rule-based segments, and REST API access. Growth at $49 adds cold outreach sequences, AI reply classification in a unified inbox, inbox rotation and warmup, and webhooks. Business ($99) adds priority support, SLA, audit log, and role-based team access; Enterprise ($299) adds custom SLA, a dedicated success manager, volume pricing, and custom integrations. Pick MailerSpark if you need both campaign and outreach workflows and can bring a sending provider; consider a newsletter-focused alternative if that dependency or breadth is not a fit.
