The Best Bulk Mail Sending software (for cold emailing newsletters, promos, spam etc).

Hello,

I would greatly appreciate some advice from the experienced email marketers community out here. I am looking to send mass emails to a large list of emails (around 1-2 million emails a month) using Atomic email sender. The default provided SMTP servers within the software will obviously not be sufficient for that volume, and hence I need additional SMTP servers to add to that rotation list. Need SMTP servers that still maintain high deliverability while being “relatively spam friendly” 

My initial search has landed me on SMTP services that are charging high 3 figures to 4 figures monthly fees for this volume. I am sure there are far cheaper and smarter ways to run these blasts?

Thanks in advance!

Scope & Use of the software: sending bulk cold mails using SMTP (or API) to mailing lists and hit INBOX

Discussion: many of us are looking to do email marketing campaigns using mailing lists obtained from various sources (Opt-ins, Scrapes, Bought lists, etc). Nowadays hitting the INBOX is harder than ever and certain measures have to be taken and implemented in order to optimize the email deliverability. Most of these measures are related to the SMTP & Proper server configs (IP, Domain, SPF, DKIM, etc). I’ll call them “Message Infrastructure”. Lets assume these are properly set-up either by you or you’re using a proper ESP with correct SPF/DKIM/DMARC setups. So you’re Message Infrastructure Health is pretty good.

Hypothesis: Okay, lets imagine that now you have a ready to use SMTP that can blast thousands of cold emails an hour. Is that enough to assure high email deliverability? Certainly not. Aside from the SMTP setup, you need to implement certain email sending techniques that lower the possibility that SpamAssassin or other Spam Filters mark your email as SPAM and direct your emails to the SPAM folder or drop you all together. Keep in mind that we’re talking about COLD emailing so you’re Sender Reputation in relation with the recipient email is non-existent.

Most important measures to avoid Spam Filters (except for SMTP/Message Infrastructure associated factors):

– mailing list quality (low or no bounce, very low or no report as spam events, no spam-traps in your mailing list) *this can be achieved by cleaning your mailing list using Email Validators and constantly purging your list for hard bouncing mails, unsubscribes and spam reports.

– message content (including attachments, URLs, message text, and headers) *here is where sending software can help increase email deliverability*

– sending patterns (volumes per batch, volumes / period of time (second, day, month), schedule consistency, etc) *here is where sending software can help increase email deliverability*

From my experience message content and sending patterns are two of the most overlooked factors when it comes to email deliverability. Most of us concentrate on the ESP related factors but SpamFilters are nowadays looking a lot at message content and behavior of the sender. Sending identical cold emails at a high second/hourly rate it’s gonna land you in SPAM or total DROP fast. Since most of the mailing lists contain predominantly Google, Hotmail and Yahoo emails, these mail services SpamFilters are very aware of what you’re doing and are very efficient in assessing your activity (and catalogue you as a spammer fast).

My conclusion for increasing email deliverability for COLD emailing:

*message content* – sending non-identical (subject, text, links, text/image ratios) emails (spin-text features)
*sending patterns* – having a “natural” emailing pattern (avoiding high peak emailing periods, temporize volumes based on periods of time) (advanced scheduling features)

So which email sending softwares are you guys using that have spin-text features and tweakable scheduling features?
