Best mass emailing solutions

An organization I consult for needs to send out around 5,000 emails to email addresses that are stored both within Outlook 2016 and Gmail contacts.

What are the best mass emailing solutions available for doing this?

Send it out through a third party commercial emailer.  If the client sends that many commercial emails out all at once through his own domain, he'll be blacklisted by the big players (Yahoo, gmail, hotmail) in a few minutes and by Spamhaus before the end of the same day.

I use Sendblaster. Wrote an article about it here;

It has an inbuilt tool (along with useful tips) that will help you avoid getting blacklisted.

That of any help to you?

Also look at Constant Contact. A number of my clients use Constant Contact for mass mailings. It has granular unsubscribe (by email subject) for people receiving the emails.

You might be served to consider deliverability also.

My preference is using MailGun for mail sending, because their per/message + per/provider debug data is stellar.

Other mailing systems... Everything's rainbows + unicorns, till delivery drops to zero, then no one can diagnose the problem... well... in an acceptable way to fix the problem.

MailGun allows sending first 10K messages/month for free.

If you send a batch of 5000 email, you must go through a warmup process for high deliverability.

This means...

1) IP Warmup - If your client pays their bills by way of their email, then use a dedicated IP.

2) Domain Warmup - These people must be jumping up + down excited to get email from you every day, or they will report you as a spammer + providers (Google, Yahoo, AOL, etc...) will first throttle accepting your email + if you keep sending, they will throttle you to 0 messages accepted.

Also, you must instantly scrub your list.

MailGun does this for you. All Unsubs, Spam Complaints, Hard Bounces (like recipient domain + MX records disappear) all get automatically scrubbed from your list... instantly...

Also MailGun fires Webhooks for every single email address state change that occurs, so you can wire these Webhook calls back into automatically scrubbing your list at your client's sending end also.

This scrubbing is handled by adding all these... types of state changes to a global suppression list, so even if you accidentally send to these email addresses again, MailGun will simply refuse to accept submission of your message for this one recipient.

This will keep your IP + Domain warm forever, so you only have to Warmup once.

Andrew Leniart,

Is there any kind of "Warmup" as described by David Favor above that needs to be completed while using Sendblaster?
Andrew LeniartFreelance JournalistCommented:
Hi IT Guy,

The "warmup" process described by David Favor I've never performed myself. It could be a requirement when using online mass mailing solutions such as MailChimp or Mailgun that David is talking about, but that doesn't apply to Sendblaster either because you're not subscribing to any type of service - you're (assuming you go Pro to unlock the premium features) purchasing a license for the software and can use it as often or as little as you like.

There's no more to pay unless you want to upgrade to the next major release. You can also use any SMTP server available to you and schedule your sends according to the SMTP server individual rules and terms of use.

I've been using this software for many years to send personalized mass mailouts and have never gotten put on a spam blacklist of any type. But then again, I've never sent "Spam" with it either.

All of my mailouts are "Opt-In" not get my message and then opt-out if you didn't want it in the first place. That's described in my article. This type of mailing campaign doesn't need any type of "warmup" process at all because receivers have already opted in willingly to receive my emails. Many are clients, many are just people that have subscribed to my newsletters over the years.

I also don't send out cold call emails asking people to subscribe. Marketing gurus will tell you to use a different email address than your domain to send your cold call emails asking for Opt-In subscribers so as to protect your domain name. To me, that's just spam, so how you choose to protect your domain name is really up to you. No warmup process is going to work if you'll be sending spam so it's kind of a waste of time in my own view.

Hope that's answered your query adequately.

Best, Andrew

One additional note about Mass Mailing + Warmups.

Many of the lists I'm working with are fairly large, 500K-1.2M, with mailings going out to all list members 3x-4x times daily, during launch cycles.

Recent Provider changes add a new wrinkle to warmups. (Provider == Google, Oath (Yahoo/AOL merger), Comcast, Hotmail, etc...)

Many providers throttle (lower rate they accept email submission) based on user complaints, ignored unsubs, ignored hard bounces, also thin content.

1) User complaints - Easy to understand. Someone either correctly or incorrectly considers your email spam + they report you to their mail Provider.

2) Ignored Unsubs - If someone Unsubs + you keep sending (common if you're using a CRM like Infusionsoft which requires you to manually scrub your list of Unsubs/Complaints/Hard Bounces) Providers consider this spam + will throttle all your sends.

3) Ignored Hard Bounces - If an email becomes undeliverable (mailbox gone) + you keep sending email, Providers consider this spam + will throttle all your sends.

4) Thin Content - Same type of penalty Google gives spamming page content. If you send email with no intrinsic value or is formatted in a way which seems to fit this conclusion, Providers consider this spam + will throttle all your sends.

So be careful sending... short news email to your large lists...

Sigh... I've been caught in this net recently for email which, so me has value + most providers agree. Other Providers disagree + flag this as spam + throttle.

I've had to switch to a system which auto-prunes recipients at some Providers, unless I specifically send a tag saying the message is rich content or deep content.

Just something I've gotten caught in lately, worth mentioning.

Fix: Best to write your email with similar though to how you'd write a content page, if you're targeting your content page for good SEO traction.
