Reliable service again

This was my third time using Mailboxlayer, specifically for the Bulk Email Verification. Like my previous orders, the results were consistent and fast. I've always appreciated their API's reliability; it just works without fuss. That's why I keep coming back for my data cleaning needs. Good to see the quality hasn't slipped.

Email verification is a game-changer

I used the Real-time Email Verification API for my small business website, and it's fantastic! The integration was super easy with the JSON API documentation. I'm already seeing fewer bounced emails. This tool is a lifesaver. I'll definitely be back for an annual plan soon and telling everyone about it!

Good for checking email lists

I signed up for a monthly subscription plan to use the SMTP Validation and Disposable Email Detection features. The ordering process was straightforward on their site, took maybe five minutes. Delivery of the API key was instant, which was great. I had a quick question about custom rate limiting, so I contacted technical support, and they got back to me within a few hours with a clear answer. The accuracy for detecting disposable emails was pretty high, much better than what I was doing manually. It made cleaning up my email lists a lot easier. It's a solid tool if you need to maintain a clean email database.

What happens if I accidentally go over my monthly request limit? Does it just stop working or do they charge extra?

N Nina 1 month ago
From what I remember, if you exceed your limit, the API calls just won't go through until your next billing cycle, or you upgrade your plan. It doesn't usually auto-charge you extra.

D Dana 1 month ago
It'll probably just stop processing requests until your limit resets or you upgrade. They don't typically hit you with surprise overage charges in my experience.

Thinking of using Mailboxlayer for a client project, but curious about their refund policy. What if it's not a good fit after I pay?

S Sam 1 month ago
I don't think they really have a refund policy as such. Usually, with API services, you're expected to use the free tier or trial to test it out.

D Dana Romero 1 month ago
Most API services like this don't do refunds once you've paid and started using it. Best to really test it on the free plan first to make sure it's what you need.

Got a promo code from somewhere, where do I actually put that in when I'm signing up? Is there a field on the checkout page?

N Noor Romero 3 weeks ago
I remember seeing a field for it during the sign-up process, usually on the page where you pick your plan or enter payment info.

Yeah, there's a spot for it. Just keep an eye out as you go through the steps to subscribe, it should be pretty obvious.

Does anyone know if they offer any special discounts for startups or developers? Just trying to find any available deals.

P Priya 4 weeks ago
I've heard they sometimes have developer discounts or startup credits. Might be worth reaching out to them directly or checking their partners page.

S Steve J. 4 weeks ago
Yeah, I think they do. I saw something about startup credits a while back, but you might need to apply or inquire about it specifically.

How accurate is the email verification from Mailboxlayer compared to like, ZeroBounce or NeverBounce? Does it actually catch most fakes and disposables?

S Shane 1 month ago
I've used it alongside another service (can't remember which now) and Mailboxlayer was pretty solid. It caught most of the obvious junk and disposables.

It's pretty accurate from my experience. I've been using it for a while now and my bounce rates went down significantly. Definitely detects disposable emails well.
