Is this secure - should I be worried?

What separates us from the other companies is the fact that Vazex is an actual ESP. Our database holds millions of subscribers of our clients, so you are in safe hands!

I ordered, what now?

After placing an order you will be requested to send us your list in Excel format, or we can get it directly from your ESP (MailChimp, GetResponse, iContact, etc.)

I don't live in USA, can you help?

We work with clients internationally, whether you are from UK, France, Canada, Australia, etc. We can help!

Will my subscribers find out?

No, we will not contact them at all. We'll run syntax, domain, and email address checks that won't notify your contacts in any way.

How does it work?

After you pay & send us your list, we'll run 3 layers of security checks on your emails. As an ESP company we know exactly what needs to be analysed.

How long will it take?

From the moment we get your subscriber list it should take 1-2 business days to complete your order.

You only work with big companies?

Of course not! We have all kinds of customers. From corporations with millions of subscribers, to individuals with only 50 contacts.

Do you have a money back guarantee?

If within 24 hours of completion, your new list is declined by an ESP, we will redo it for free. If declined again, we will offer a full refund. Please read our refund policy.

Customer Reviews

All I can say is we're EXTREMELY satisfied with your service & prices. Our lists always get accepted on MailChimp with top deliverability!
- Belinda W.

Account reputation fell to 82% due to our list going stale. Thanks to you guys it is back at 96% and improving.
- Tom R.

It isn't easy to maintain lists with millions of contacts, especially with some subscribers being 3-4 years old. This way we keep it clean and fresh.
- Steve K. Tropicano Juice

I only have about 620 subscribers on my blog, and with few bad emails I get high bounce rates. So this service is perfect for me. Thank you :)
