Sending limits of various Email Service Providers
Below you can find a short alignment of sending limits that apply with four Email Service Providers (ESPs) that are most commonly used with Woodpecker.
Important: Any new or inactive mailbox needs to be warmed up before sprinting with the delivery of your emails.

Take care of deliverability of your emails
Every email provider needs to rely on anti-spam filters that protect their network from spammers – these can be considered the "second limit" (which is never made public for security reasons). Thus, while there might be no strict limits officially, there is a list of good practices when sending large volumes of emails that help avoid having your emails classified as spam.
Bear in mind that quality cold outreach should never aim to hit these limits; while striving for "quality, not quantity"; the key to success is to send highly personalized emails.
