Unsubscribe rate is the share of recipients who opt out after an email. A small, steady rate is normal list hygiene; a spike is a signal that a send missed the mark. This free calculator gives you the rate per campaign.
Delivered, not sent, for an accurate rate.
Opt-outs from that send.
Watch for spikes that flag a misstep.

Often below 0.5% per email. A higher rate usually means the content, frequency or audience match needs attention.
Send relevant content, set expectations on frequency, and segment so people get what they signed up for. A clear value beats a big list.
On Klairova you can segment your audience and automate the right sequences, so people get content that fits them and stay subscribed.
