Hi I own a small and growing I.T company we deal in app and web development and technical support mostly. I would like to add a new service to our portfolio (email marketing), but has no knowledge of how this actually work. We know how to create the email template html also know that we have to build a clean email list which user has actually subscribed to and double opt-in and all. But the biggest challenge is.

Which server should we use to send these emails.
Domain , IP that will get less considered as spam.
Cms or any other software which as good rating to send these bulk email from
Any special request we need like understanding with ISP and so on?

Please feel free to add any suggestion

— good to see the double opt-in thinking; ’s anti-spam caution is valid. Sending only to confirmed subscribers is lawful, but U.S. commercial mail must still follow CAN-SPAM rules (accurate headers, a working unsubscribe, a valid postal address, etc.), so compliance and clear consent are essential. (ftc.gov)

For a small agency handling clients with ~100 addresses each, the practical route is to use a reputable ESP (Mailgun/SendGrid/Mailchimp/SES/etc.) on shared IPs at first. ESPs handle domain authentication, bounces, suppression lists, feedback loops and blocklist monitoring — all the operational pieces that make deliverability reliable. Dedicated IPs and custom routing are worth it only once volume and consistency grow; providers publish thresholds and guidance. (help.mailgun.com)

Technical checklist to avoid being treated as a spammer: authenticate each sending domain with SPF + DKIM (and DMARC for bulk senders), ensure reverse DNS (PTR) matches the sending hostname, use TLS, include a clear unsubscribe and List‑Unsubscribe headers (Gmail requires one-click for large senders), process bounces/complaints and remove inactive addresses regularly. Monitor provider dashboards and Google Postmaster Tools to watch spam/complaint rates. These items directly affect whether mailbox providers accept or throttle mail. ()

Operational tips for multi-client work: send from a client-verified subdomain per customer (isolates reputation), use subaccounts or IP pools for larger clients, throttle/stagger sends to avoid sudden spikes, warm up any new dedicated IP slowly (or use providers’ automatic warm-up features). No special ISP "agreement" is usually required when using a proper ESP — the heavy lifting is done by the provider, but the agency must enforce list hygiene and authentication. (sendgrid.com)

In short: keep strict opt-in and hygiene, authenticate domains, start on a trusted ESP with shared IPs, and only move to dedicated IPs + warm-up when steady volume justifies it.

the standard way to spam people is to buy a botnet and use that. And we're not here to help you harass people with spam and/or do other illegal things.

You are getting me wrong.

I do not want to spam people i want to offer the email marketing service to my clients. I will help them build their mailing list of subscriber, we will not send to anybody who is not on the client emailing list.

The question is if my clients has a list of 100 subscribers when i send these email even if they have subscribe will my isp or even spam filter will see that as spamming because im sending lot of email at the same time, If I have 10 client using my service and depending on how frequent they want to do it.

So is there a special server, software or agreement with isp i need to have? (im not talking about botnet here) do i need an smtp relay server or a trusted domain name these kind of things so these email can safely be delivered to these subscribers inbox?
