Checks email lists for invalid, disposable and risky addresses before you send, in bulk or over an API.
The catch: Usage is metered as 500 verification credits a day on one code (4,500 a day at five codes) plus a one-time bonus of 100K credits, so a single huge list can take days unless you stack codes.

Cold email outreach with AI-written personalization, sequences, warm-up and a shared inbox for replies.
The catch: One code caps sends at 50,000 and AI at 2,000 credits a month; unlimited sends and the AI reply agent arrive only at 10 stacked codes ($790).
Email MarketingAppSumo4.4/5 on AppSumo (511 reviews)
Simple email marketing for creators: campaigns, automations, forms and landing pages.
The catch: The $29 license is capped at 5,000 contacts and 300,000 lifetime email sends, not per month. Removing SendFox branding costs $10 a month (Empire add-on).
Email MarketingAppSumo4.0/5 on AppSumo (342 reviews)
Email campaigns and automations sent through your own SMTP provider, such as Amazon SES, Mailgun or SendGrid.
The catch: You still pay your SMTP provider for every email sent, and each tier caps subscribers (5,000 on the $19 tier).
