I'm using subdomains to segment the list. And it's a combination of spf/dkim/from all being from the same subdomain, say, sub2.domain.com.

I have MX record for sub2, but do I also need an A record?

I know that without an MX or A record some receiving MTAs will block it as "Sender address rejected: Domain not found". But if I have MX record, should I also set up A record?

Do receiving MTAs or spam filters actually check that?

I have a prompt where I ask the model to produce a short article (like a post-size, maybe 250-350 words) on a randomly-selected sub-topic/angle in some specified niche.

And I run this prompt over and over to get one article per run.

For example, I instruct the model to write a short article on lawn care and mowing and pick a random angle for the article that would be interesting to the audience in lawn care.

And I run this prompt repeatedly to get more articles. One at a time.

Initially I get a variety of articles. But after maybe 50 runs, the model starts repeating itself.

I tried feeding it the gist of all previously-generated articles into the input and instruct it not to repeat those that were provided previously (that I'm providing in the input for the given run). That seems to make things worse. As the model discards the "do not repeat" instruction, and uses keywords/context from previously provided outputs to tunnel vision into them. So it's actually worse.

I tried keeping one long session to produce multiple articles instead of having one run per article. But the model drifts quickly and it become either garbage or goes in circles repeating the same angles.

I tried providing it with random seed word on each run. That seemed like an awesome idea, but ended up going in circles too. Just using the seed word and still converging on the same limited list of angles over and over.

Does anyone have any ideas on how to make a model generate unique angle on each run when I ask for an article in a given niche?

I called Cub Cadet support number, and the person there assured me the ultra blades provide more lift. Which makes sense, but looking around various (scarce) sources, some mention those blades are identical. They are just a new packaging model number.

I want to install a bagger on a Cub Cadet Ultima Z2. And I'm trying to decide if it's worth getting those Ultra High-Lift blades or not. Don't want to buy them if they end up being exactly the same as my stock blades that came with the mower.

Obviously something.mybrand.com is a subdomain of mybrand.com. And somethingmybrand.com is a different domain.

But I've seen people saying here "I'm using a subdomain to send out my sequence from emailmybusiness.com and only send transactional email from mybusiness.com".

The problem with this is the advice then ends up being misunderstood. If people really mean you need a separate domain while saying "subdomain", then does it mean there is no point in using actual subdomains?

It's the same with "send a plain text email". And then you talk to the person more and you realize he has no idea that he is talking about a text/html multipart that just doesn't have any images in it. That's what he calls "plain text email". As opposed to sending an actual text/plain email. Which again completely changes the meaning of the advice being given.

So what's the consensus here? After realizing how people misuse terminology while saying "I've been doing this for 20 years", I'm beginning to doubt how I understand much of the advice received in this sub. That's not good.

Another one is "inbox provider" referring to spam companies that provide throw-away inboxes to use as reply addresses instead of actual inbox providers like Gmail.

Anyway, rant over. What's the deal with subdomains? Are they beneficial in helping split reputation or does all that advice about using subdomains actually refer to using different domains?

I'm moving my mailing servers from a location where I hosted them for about 20 years. I have a range of IP addresses assigned to me by the hosting provider, and they created a small AS and listed me as the assigned party for that range.

These IPs have sender score of 99, and had for a very long time.

I'm reorganizing my mailers and moving to AWS EC2 instances with AWS SES being backup if there is ever a problem mailing directly from an EC2 instance with maybe another provider (traditional hosting) as a second backup option. But mailing plant to mail from EC2 instances.

I'm been mailing from EC2 for two years now. Micro instances work great. And elastic IPs seem to work fine. I have AWS elastic IPs I've been using for a while now that have good reputation. I don't do anything shady, so no problems so far (knock on wood).

So to my question:

I'm preparing to move all my mailers to EC2 and give up my old hosting. If I warm up new IPs for a few months, is it any different than IPs that have been mailing constantly and with good reputation for 20 years? I figure it doesn't matter. After a few months of history nobody cares. But maybe I'm missing something important? Any advice on this?

I'm mailing daily, if that matters. So subscribers get multiple messages per day. Constant flow.

I did some reading in this sub, and I understand that the standard recommendation is to get something more expensive. Nevertheless, if I wanted to get an entry-level residential zero turn mower, which of these brands should I choose? Or does it not make any difference?

I have about 1/2 acres of mostly flat land. I'm in Florida, if that matters. I can fix stuff when it breaks.

I really don't want to spend more than $3500. Maybe even less if I can find a deal.

A used mower of a better brand would be fine too, but I'm concerned that people don't sell good mowers. It's not hard to find a used car in good condition. I'm not sure if it's as easy to find a used mower in good condition. So I'm looking at new with cheaper brands to stay withing my budget.

I mail out daily at 6AM eastern time. My concern is it's too early in the day for people on the West Coast. If my email ends up in primary (which is the goal), it puts out a notification on their phone. Wakes people up, and they get pissed.

So I tried mailing at 11AM eastern. But I get more overall clicks when I mail at 6AM.

I'm back to mailing at 6AM, but I keep thinking this isn't optimal. I have no way to segment users into time zones reliably. (I tried using their history click data to determine those that can be mailed earlier, but it's noisy and unreliable sometimes even backfires.)

What's the consensus when mailing to USA audience and there are people on both coasts? What's the best strategy for a daily mailing when it comes to time of day?
