Target eCPM-

Cold IPs: $0.35 or less
Warmed IPs + Good Rep: $1.25+
Warmed IPs + OK Rep: $0.50

1 Domain / 1 IP / Segregated Data: $0.75-$1.50
1 Domain / Many IPs / Seg’d Data: $0.25-$0.50

Before sending even 1 email, cull your GI list by using a simple bell curve to exclude domains that exist outside of 1 standard deviation from the median email IDs per domain. If you don’t know how to do statistical math like SD, then just exclude domains that have fewer than say 100 email IDs associated with them. If you don’t know how to do that, you got probs and may want to consider doing gay porn as it will pay you better. Don’t discard these domains, just don’t mail them for now…

OK! You can see what you should be making mailing correctly from these approximate figures. I’m assuming you know what ecpm is, and that for every 1000 emails sent you will make that amount in revenue…with a $1.00 ecpm you send 1M emails and earn $1,000 in revenue.

Factors like quality of data and offers matter too, but we’re not getting that deep for now.

Main Difference of Mailing TLD vs GI

The main difference in mailing these comes down to resource management.

TLD/Big 4/Cables = long term, reputation building, IP health and warming

GI = churn-n-burn

Both offer fantastic revenue earning possibilities. Both come with their own unique problems. Both require constant learning.

The Truth of Inboxing GI

Truth is inboxing GI is easier than TLD, wayyy easier… doesnt need much ip warmup as compared to TLD…

You said big companies spend tons of money on firewall etc. NO, don’t u think they might have better things to worry about instead of spending tons on spam filter?

Free providers(hope u meant tlds) have hundrends of millions of userbase so they have an incentive to work on, protecting millions of users from receiving spam.

GI = General Internet, it means all the emails apart from TLDs and cable domains(read below).

TLD = Gmail, Yahoo, hotmail, aol etc (the big ones)

Cable = Comcast, Cox etc email addresses.

There is no special thing for warming up GI as long as ur ip/domain isnt blacklisted u should be fine.
U can easily go high volume per ip without fear of hitting spambox. BUT the issue with GI is ips get burned easily so always segment ur data from GI and TLD and have separate servers for both.

Five Main Factors of Deliverability Issues

If one is simply looking to ping (i.e. perform an SMTP check) on email addresses, which is what the companies listed above all do, then you’re not going to be solving your deliverability problems.

Deliverability issues are the result of five main factors in the following order of priority:

  • The existence of spamtraps and/or honeypots
  • Excessive spam complaints – .3% (i.e. 300 complaints out of 100,000 sends) is the typical threshold used by ISPs.
  • Exceed this threshold and a dynamic block will be put up, preventing the delivery of any future emails for 24-48 hours.
  • Exceed this multiple times and you’ll find yourself blocked and/or blacklisted for good.
  • Exceeding bounce rate thresholds – 10% is the typical threshold used by ISPs but this can vary significantly across ISPs, some of which are also factoring engagement metrics into this calculation and their determination of whether or not you’re a worthy sender.

Pinging is discouraged by many ISPs, which will shut down attempts over a certain number or provide back inaccurate information so any service that simply performs pinging only might result in more issues than you first started with as you will end up throwing out good addresses with the bad. Furthermore, pinging an email address, even if this could be 100% accurate, will not flag spamtraps, honeypots, heavy spam complainers, “role” accounts that go to multiple accounts, and other malicious addresses that can destroy one’s email program.

Accordingly, marketers need to employ a service that blocks deliverable but toxic addresses, corrects hygiene errors, and validates all email addresses that survive the first two screens. Doing this properly requires expertise, experience, technology, and a knowledgebase built over years of reviewing billions of email addresses.

Getting More Datas, IPs, and Domains to test

Honestly, i would rather focus more on getting more data, ips, domains. Then once done, i would get more data, ips and domains….assuming your system is delivering and inboxing.

All post delivery analysis such as mentioned are actually good but in mailing you have to focus on delivery, inbox, and then engagement.
Even if you have 10000000000% engaged data…..

The Key of Mailing Succesfully

Again the key is NOT mailing for revenue, but instead simply to engage the recipient to determine if the address is active. Then you take the cleaned data and mail for revenue.. I think people sometimes make the mistake of ALWAYS trying to maximize revenue on every drop when in fact some toilet flushing, and dumping of inactive data, will improve delivery and you’ll make more money mailing less…

Mailing Vertical

I think assuming data from “vertical x” will respond to offers in the same vertical is a mistake in and of itself. The thing to do IMO is try a high clicker type of offer like coupons, zip/email submits – something well branded that will illicit that click you’re looking for. Load up something completely different and give it a shot; doesn’t sound like you have much to lose rev wise at least!

What Emailing Business is Mainly About

Emailing business is mainly about

1. data (good or at least fresh)
2. ips (and maintaining reputation – see #1) [several for Big4 Broadband / 1 a day for GI]
3. MTA supporting current standards (DKIM, SPF, DMARC, ip throttle, message throttle, back offs, etc…)
4. domains (for infrastructure – froms, clicks, rdns, fbl, etc…) some of this doesn’t apply to GI but to Big4 Broadband

As for offers, subjects, format, servers, networks – DO 1-4 first !
The rest is just tweaking and optimizing.
These are also important but without 1-4, it will be an uphill battle.

Even if you have the dumbest subjects in ugly broken english text format
promoting a used condom with a flaky network or advertiser, YOU WILL get opens and clicks
and maybe 1 convert if 1-4 is in place.
