Email Verification Tool

I have created an email verifier but I am struggling with solution providers for infrastructure. I am looking for a web hosting that has ports for smtp open for example the port 425, and some place which supports IP rotation. I would repeat this isnt for send cold email blast but for testing my email verifier tool.

Look into cloud providers like DigitalOcean or AWS that offer flexible server setups allowing custom port configurations; additionally, consider exploring services specializing in residential proxies for IP rotation which are essential for realistic verification testing. Ensure the provider's terms of service allow for your intended usage to avoid any issues.

You can also use mailgun, they offer a free plan for SMTP.

PHPMail/Host mail is sometimes flagged as spam as IPs are flagged as spam due to previous abuse.

Most standard hosting providers block SMTP ports by default to prevent spam. For a verifier tool, you should look into 'Bulletproof VPS' providers or specific cloud platforms like OVH and DigitalOcean, though they often require a history of trust. For IP rotation, integrating a dedicated proxy service like Bright Data or Oxylabs is usually more effective than relying on the host's infrastructure.

Mailgun provides hosting ?

No, it is an SMTP provider meaning you get SMTP credentials or you can utilize the Mailgun API.

You still need a hosting provider, and your script needs to support SMTP utilization.

Once it does, you just imput SMTP details within your script and bam you can start sending emails.

THis bypasses the need for asking your host for email access. WHich is generally better as their IPs are usually flagged as spam for email.

AI slop spam.

Maybe try Contabo or OVHcloud?

You’re correct to clarify that this is for an email verifier and not for cold emailing, because many shared and managed hosts block SMTP ports and IP-level controls precisely to prevent abuse.

For what you’re describing open SMTP ports and IP rotation you generally need infrastructure you control at the network and firewall level, not typical shared hosting. Conceptually there are two components you need to think about:

1. Servers with open outbound SMTP ports. Most mainstream shared hosts block outbound SMTP (25, 465, 587 and high-numbered ports) for security reasons. To have full control over which ports are open you want.

2. IP rotation, Having multiple public IPs on a server and cycling through them. Using a pool of VMs each with its own IP. Using a proxy service that provides HTTP/SOCKS exit IP rotation.
Most basic VPS providers give you one primary public IP by default, with paid options to add additional IPs. True rotation usually requires either. A service that supports a range/pool of IP addresses you control. A proxy network that supports stable rotating exit IPs (residential or datacenter proxies) if you need many different source IPs.

What's wrong with the two providers I suggested?

You didn't suggest anything, you copy/pasted AI slop. If you have reading capabilities, read the last sentence of the op and then check your ai spam again. AI is only valuable if you are already smart yourself. Just saying.

AWS is not for email validation testing and has closed SMTP ports on default and you will get banned instantly anyway if you are having high bounces. Also, onboarding for SES (not AWS) is lengthy and requires KYC of company and so on.

DigitalOcean has closed SMTP ports and aren't even really opening them anymore, maybe on a case-to-case basis but unlikely.

I think there's been a bit of a miscommunication here. EternalEsper, your suggestions about exploring cloud providers like DigitalOcean or AWS, and considering residential proxies for IP rotation, are spot on. Amaz0n, regarding your suggestion of Contabo or OVHcloud, could you elaborate on how these providers might be suitable for the OP's needs, specifically in terms of open SMTP ports and IP rotation? I'd love to hear more about your thought process behind these recommendations.

Pick whatever has fresh lists and low bounce rates, saves you headaches later.
