Phone numbers are more
valuable than emails

Data suggests that 98% of visitors won’t buy on their first visit, and 55% of them leave your website within
the first 15 seconds of their visit. Most will never return again. You have to capture the 2% who are ready to purchase immediately,
but you also have to target those who are not ready to buy yet – and collecting phone numbers is a great way to do that.

In comparison to email marketing, SMS has proved to be more successful. It has a 45% response rate and a whopping 98% open rate.

Personalize messages
for mobile users

Capitalize mobile traffic by displaying personalized messages to them, e.g. you can offer free callbacks, or promote special offers for them.


Gather quality leads and build trust by helping your most engaged visitors solve their issues with valuable and downloadable guides.

Let customers ask
for a callback

If you offer a more complicated product/solution, your visitors might have multiple questions before the purchase. You can easily collect phone numbers by offering a callback.

We immediately realized the effectiveness of OptiMonk, and it brings great results to this very day. We were able to collect 12K+ new signups to our phone number list by offering callbacks.

Offer custom quotes
on the phone

Instead of displaying all pricing information on the website, why don't you offer custom quotes for some services? It gives you a chance to collect phone numbers and talk to prospects on the phone.

We have been able to A/B test our popups with good results. We have been seeing way more subscribers. Definitely worthwhile. Thanks OptiMonk!
