At a glance
Free advertising calculators for CPM, spend, impressions, CPC, CTR, and eCPM.
CPM Calculator is a free browser-based toolkit designed for advertisers, marketers, publishers, media buyers, freelancers, and small businesses that need to plan and evaluate digital advertising campaigns. The main calculator lets users enter any two values among CPM, total ad spend, and impressions, then instantly calculates the missing value. This makes it easy to estimate campaign costs, compare media plans, and check whether a proposal fits an available budget. The website also includes focused calculators for CPC, CTR, eCPM, break-even ROAS, campaign reach, campaign comparison, and YouTube earnings. Each calculator explains the formula, shows the result immediately, and keeps the workflow simple for users who do not want to build spreadsheets or search for formulas. The tools are useful for planning new campaigns, reviewing past performance, comparing advertising channels, and communicating estimates with clients or teammates. CPM Calculator works directly in the browser and does not require an account, installation, or subscription. Users can select a currency label, enter their campaign data, and receive results without hidden currency conversions or unnecessary steps. The responsive interface works on both desktop and mobile devices. Unlike a large advertising platform, CPM Calculator is independent of any particular advertising network. It focuses on transparent calculations and practical planning tools that can be used across display advertising, social media campaigns, video advertising, publisher inventory, and other paid media channels. All core calculators are free to use.
The self hosted email platform you own on your AWS - transactional, marketing & MCP
Sendbunny is a self-hosted email platform that deploys into your own AWS account and uses Amazon SES for delivery. It combines transactional email, marketing campaigns, unlimited contacts, templates, analytics, suppression management, multiple domains, team inbox, API access, and MCP support in one platform. It's built for startups, SaaS companies, fintech teams, developers, and agencies already using AWS or Amazon SES, especially teams that want to avoid growing monthly ESP bills and keep control of their customer data and infrastructure. Teams using hosted ESPs often face rising costs as contacts and usage grow, vendor lock-in, account suspension risk, and fragmented tools for transactional and marketing email. Raw Amazon SES is much cheaper, but teams then have to build the entire product layer around it themselves. Sendbunny fills that gap. Unlike Resend, SendGrid, Mailgun, Mailchimp, and similar hosted platforms, Sendbunny runs inside the customer’s own AWS account. You use your own SES account, keep your data and infrastructure under your control, get unlimited contacts, and pay a $199 one-time license instead of another recurring platform bill. The email platform you own - transactional, marketing & MCP, on your AWS.
