Pay-per-use tools worked better for us since we don’t clean huge lists every day. Subscriptions only made sense when volume increased.

We also started running quick checks right after importing new contacts. Catching invalid emails early saved us from issues later in campaigns. It’s a small step but adds up.

For us, ZeroBounce has been the most reliable for bulk uploads. It’s not the cheapest option, but when you’re sending at scale, I believe that accuracy matters more than saving a bit on verification. Fewer bad emails going out made a noticeable difference.

&lt;p&gt;&lt;span style=&quot;background-color: transparent; color: rgb(0, 0, 0);&quot;&gt;&amp;nbsp;How often do you clean your lists — before every campaign, monthly, or only when bounce rates rise?&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;We’ve moved to cleaning lists before every major campaign, not just when bounce rates spike. It felt excessive at first, but it actually stabilized our deliverability over time. Tools like ZeroBounce helped, but the consistency in process mattered more than the tool itself.&lt;/p&gt;
