Fast Way to Warm Up Cold Email Servers?!

View attachment 384647
Mail In a Box comes with an API for advanced usage. You just need to send post requests to your mailinabox server for creating a mailbox. That request can be generated from anywhere like a Google Sheet/ an application.
Oh I get it. Thanks for these posts really help.
Is there a way to setup mailinbox on a server for free or do we need to buy a server.
I don't know if you know but oracle offer a free plan can these work?

I never used free servers for email servers honestly so no idea. I buy VPS from Contabo and Racknerd mostly for cheap like 5$-8$. They work best for us and I have more than 4-5 mail servers right now.

Oracle might not open port 25, you will need port 25 open if you want to send emails from your server.

Yeah makes sense. I will need to look into VPS servers more never used one before, we are basically setting mailinabox on ubuntu right?

Thanks for these posts I hope you succeed in whatever you are doing :)

Yes on an ubuntu. Try to install it on an Ubuntu 18.0 LTS for stable performance. Newer OS versions act up a little with Mailinabox latest releases.

Thanks I'll keep that in mind. I will need to lookup how to set it up.

The warmup tools like Instantly, do you subscribe to a paid plan?
You also mentioned warmup tools I never heard of before and was surprised they offer a free plan.


I'm trying to set everything on a budget since I don't know what I want to do will work or not. Just don't want to waste a ton of money on something unproven yet.

Yes all of the plans I use are paid. Some do offer free plans for you to test them out as of now.

Its easy to setup a normal google search gives you the steps to run to install mail in a box.

It works for sure just depends on how big volumes you want to send and how to load balance the volume with multiple domains and servers to not hit the spam box.

Yeah what you are saying I feel confident it works. I meant what I want to send and stuff I don't want to invest too much into this and find out my idea doesn't work.

I don't need crazy volume max 300-500 emails/day. I assume I can use multiple domain to spread using 1 mailinabox on 1 VPS for such volume?

Yes 5 domains with 4 mailboxes each = 20 mailboxes.

Each mailbox sending 20 emails out= 400 emails a day.

Send 20 cold emails and 20 warmup emails from the mailinabox server.

1 mailinabox server can easily handle this.

How are Contabo and Racknerd with spam complaints? Guess you get some when its cold mailing.

Got kicked from Contabo once in 2020~!
Racknerd has never so far. Our IPs are all green in Talos so we got good reputation due to the volume of warmup done.

yeah.. I did also do instantly and warm and did cold emails. But got complaints so had to move server.
 
The fastest way to warm up an email server is by gradually increasing your sending volume while focusing on positive engagement. Here's an optimal approach:

1. Start with low volumes: To build a good sender reputation, send 10-20 emails daily to highly engaged recipients (friends, colleagues, or existing contacts).
2. Increase gradually: Increase by 5-10 emails/day each week. Avoid sudden volume spikes to prevent deliverability issues.
3. Positive engagement: Encourage recipients to open, reply, and click links in your emails to signal to email providers that your content is valuable.
4. Use warm-up tools: Services like Warmbox or Lemlist can automate the process and help scale faster by mimicking natural engagement across various email providers.

If you start with this plan, you can be ready to send larger volumes in 3-4 weeks.

I had a look at these and I couldn't find any cheap options cheapest are $17/mo or something, which VPS do you use? I'm totally new to this so I might be missing something.
I appreciate the reply.
