ESPS

ESPs commonly refers to extrasensory perception, a proposed set of abilities that enable information gathering or influence through means beyond ordinary senses. This umbrella includes telepathy (mind-to-mind communication), clairvoyance (perceiving distant or hidden events), precognition (knowledge of future events), and psychokinesis (affecting physical systems with the mind). In parapsychology, ESP is studied as a potential phenomenon beyond conventional sensory channels, but the topic remains controversial. Critics point to inconsistent results, small effects, and methodological challenges, and the mainstream scientific consensus is that robust, reproducible evidence for ESP has not been established.

ESPs also denote Espressif Systems’ line of microcontroller-based devices, especially the ESP8266 and ESP32 families used in Internet of Things projects. These low-cost components combine a microcontroller with wireless connectivity (Wi‑Fi, and in some models Bluetooth), enabling compact, energy-efficient IoT applications. They enjoy broad developer support and can be programmed with multiple toolchains, including the Arduino IDE and the official ESP-IDF. Variants differ in processing power, memory, and security features, and the ecosystem includes development boards, modules, and peripheral libraries suited to home automation, sensors, and embedded systems.

Another common meaning is Email Service Providers, organizations that handle bulk email sending for marketing, newsletters, or transactional notifications. ESPs supply list management, email templating, delivery infrastructure, sender reputation management, and analytics. They help manage compliance with anti-spam laws and data privacy requirements, and aim to optimize deliverability and engagement. Selection typically depends on scale, integration options, targeting capabilities, and security considerations.
