Labnify

What is Labnify?
Labnify hands you a pre-warmed SMTP relay, campaign dashboard, and HTTP API so you can blast outbound email without standing up your own mail servers. List imports, automation workflows, open and click tracking, webhook delivery, and opt-in form builders sit in one panel, with DNS verification as the main setup step before day-one sending.
Most ESPs sell seats or contact caps. Labnify prices by monthly send volume instead, with unlimited contact imports and unlimited sending domains on every tier. That makes it a fit for cold outreach and bulk B2B campaigns where list size would blow up a typical marketing plan, though inbox placement still depends on your content and list quality.
Outbound marketers, lead gen teams, and agencies running cold email or newsletter blasts at scale are the core audience. Developers can wire Labnify into apps through API tokens and webhooks, while agency tiers on Platinum and above add subaccounts for reselling send capacity to clients.
ChatGPT Services

What is ChatGPT Services?
ChatGPT Services hosts Gmail add-ons from Klart AI that write, translate, summarize, and analyze email inside your inbox. AI Mail Assistant adds reply generation, draft polishing, 13-language translation, ChatGPT Q&A, and tone or ethics analysis to Gmail through the Google Workspace Marketplace.
Unlike standalone ChatGPT tabs, these tools live in Gmail's sidebar so you generate replies, insert drafts, and translate threads without switching apps. A separate AI Label Assistant product auto-labels and archives mail on an hourly schedule using your existing Gmail labels, with custom instructions when label titles alone are not specific enough.
The suite also includes Klart Prompts for GPT, Midjourney, and reverse prompt engineering. Plans start with 10 free AI Mail Assistant requests per month, paid tiers from €4.99 monthly, and Stripe or PayPal billing with cancel-anytime subscriptions.
