Best way to send emails just to test bounce back

Hi all,
I am scraping email addresses and have a lot of Yahoo emails on my list. Unfortunately, Yahoo disables a lot of email accounts if they aren't used for 6 months and this is registered as a bounce when an email is sent to that email address. An email verifier API doesn't work on these accounts because they are still registered as existing but are disabled. The only way I've found to detect if they are disabled is to send emails to them and check if a bounce comes back. I really need to clean the list. Does anyone have any recommendations how to do this? I don't even care if the email goes to spam, in fact I would prefer that. I purchased hotmail accounts from someone here and even set up different IPs for each account and tried to send to a Yahoo account using SMTP via that proxy that I knew was disabled and the account ended up getting banned. I need a reliable method to do this. If there is an email sender that isn't as easily banning as well, I would love any suggestions.

following....

I get your point. I want to do the same, but currently don't have the time.

Here's the idea:

1. Get high quality email accounts, for example Gmail. Get an account creator script, or purchase a bot, or make it yourself.
2. Create a warm up pool with those accounts. You can either use any of the paid warm up services, or create an automation to automatically, with random timing open, reply, classify emails. These accounts need to have high quality proxies attached to them, as Google is notorious against bots and automation software. They do not like it (of course). What I recommend is getting a cold email software subscription or lifetime deal, since they have FREE warm ups. I personally have a few LTD deals for cold emails, and have unlimited sends.
3. Add created emails to sending tool.
4. Start sending a few emails per day, back and forth with either emails you've created, or emails from warm up service, then increase sending numbers - gradually.
5. After you've properly warmed up your email accounts, you can start sending to yahoo email domains.

PRO TIP: Send emails to customer service emails since most of them have autoresponders, and increase positive signals towards your account

Now, the template should look COMPLETELY naturally. Which means, that you must not send giberish, or any promo copy. No links as well. It could be something like:

Subject: Thank you {{firstName}}

OR

Subject: Coffee next week?

Or whatever subject lines people send when sending emails to friends. Template should be naturally-sounding as well. Avoid spam trigger words.

Another thing, introduce spintax, typos, different synonims, and most importantly timeouts! Spintax is important since it creates an unique email, which will reduce chances of bans.

If my calculations are correct, with just 100 gmail accounts, you should be able to verify a few thousand Yahoo emails per day after 2 weeks. Standard email warm-up period is 3 to 4 weeks.

Good source is needed, since the accounts will get burned from time to time. But, this way we can minimize account bans.

PS. Need to verify bounces as well. If anyone is open for collab, lmk

Interested in collaborating. I already have some hotmail accounts I've been warming up and had to add SIMS for verification which seemed to make them less likely to block. I need a reliable place for hotmail verifying sims. I also have some pretty good proxies that seem to be doing the job. Do need help with the autoresponders.

Check out sms-activate.org

They have bunch of SMS verification options, and also an API endpoint.

Do you purchase all email accounts or you are using custom scripts/software?

I purchased some aged ones but can program a bot to do the same. In order to really get a good bot, I need to make sure sims I purchase are reliable because if you try too many times to add different numbers in outlook you can get flagged. I am working on something else so just needed something quick that would do the job before I spent my own time with bots. But could definitely collaborate on sending different emails where wordage changes and work with some autoresponders. Right now Im just sending some emails to my own email addresses so not sure if that will lead to any blocks. Two days ago I was blocked but managed to get back in by adding a phone number so I think PVA is key here. I have tried different Sim providers but a lot of them the activation code doesn't go through and are unreliable but I will check out the one you send. I purchased some dedicated proxies that have ports for SMTP and IMAP open but would really like to make my own somehow in a cost effective way if I really want to scale this. Im only working with 12 email addresses right now because I only bought 11 dedicated proxies. Most cheaper proxy providers block smtp and imap ports which is annoying, so have to find a good cheap option that doesn't block. I already have the raw automation in Python to send the email and wait to see if bounce comes back, just need to scale.

Is there any reason you wouldn't just use one of the email verification services for doing this?

Yahoo disables accounts that aren't used for 6 months to a year. They still register as valid on the verification service because technically the email address is still available. But these emails still come up as a hard bounce which is extremely damaging to the domains I've been sending through.
