Maintaining your email list’s hygiene is akin to regular health check-ups; the frequency depends on individual needs but shouldn’t be neglected.
Factors like industry type, subscriber acquisition rate, and campaign nature influence the cleaning schedule.
However, always keep an eye on metrics.
A dip in open rates or a spike in bounces might signal it’s time for a clean-up.
In essence, while bi-annual checks are a good starting point, align your cleaning frequency with your business’s unique rhythm to ensure your email marketing remains effective and efficient.
