Woodpecker is an email tool that enables you to send cold email outreach and inbound lead nurturing email messages and follow-ups automatically, but one by one as if you were sending them manually. If you get a reply, further follow-ups are automatically stopped. Replies from different address, forwards and autoresponders are also detected. Personalize cold emails, track clicks and opens, and collaborate with your team.
Use your real email signature: Just like using a real reply-to email address, you want to use real contact information within the email and the best way to do that is to include your contact details in the email signature. Giving your readers the opportunity to contact you or connect with you online is a great way to be personal and build a relationship with them.
Keep the subject line and pre-header short: The subject line is crucial. Keep it short so the reader knows exactly what the email topic is about. And the pre-header text (also known as snippet text), don’t let it go to waste by using “To view this email in your browser…”. Instead, summarize the email or include a call to action (i.e., Use “FREESHIP” to get free shipping).
The downside of just making offers is that they’re not useful on their own. People on your list won’t receive any value from you unless they buy what you’re promoting, so they have little reason to stay subscribed. That’s why this email marketing strategy doesn’t work alone. And it’s why many e-commerce sites struggle to keep people interested. There are a few exceptions (e.g., Groupon) that rely entirely on making offers—but then the reason people joined the list was specifically to receive those offers.

Wow such a detailed review! I have tried MailChimp before and I found it too expensive. After that i’ve signed up to Mailerlite and got hooked. It’s either free or cheapish depending on your subscribers’ lists. With other email software providers, you’d need to make an investment even if you’re running a small shop or a blog. And let’s be honest, not everyone of us can afford it :)

Fantastic article, thank you! I was wondering if I could ask some advice — we are only a small company that doesn’t need automation or a CRM, we just want to be able to send out monthly emails to 6000+ subscribers that can be categorised into industries or groups. We don’t need bells & whistles. Due to our industry, the chunky CRM doesn’t integrate into a.n.y.t.h.i.n.g. so it’s all very labour intensive but lucky for them I do love a spreadsheet. Thanks in advance for the advice.
Mailchimp is a very well-known email marketing tool that integrates with popular apps and services like Salesforce, Eventbrite, Google, Twitter, Facebook, Shopify, and SurveyMonkey.

Mailchimp Mobile Dashboard enables you to check in from anywhere.
Ask for the right information upfront: Great personalization starts way before you hit the ‘send’ button. It all starts with your sign up form. Without data such as name, company and location, you will be very limited with your personalized communication. Remember to only ask for the information you need, rather than the information you want. This is one of the ways that GDPR has impacted marketing teams.
On a more basic level, AI improves email marketing mechanics such as A/B testing and smarter audience segmentation. This can have immediate benefits in terms of optimizing your marketing strategies for different customers and sending the right content to the right people. On a more advanced note, AI can actually optimize email content for specific audiences and product campaigns. Additionally, it can help with personalizing email content right down to the individual customer level, depending on how much information you can feed it from your CRM and sales systems. AI delivers strong capabilities, which means determining exactly how a potential email marketing service has implemented AI should be key criteria for most marketers before purchasing.
Take the email below from Paperless Post, for example. I love the header of this email: It provides a clear CTA that includes a sense of urgency. Then, the subheader asks a question that forces recipients to think to themselves, "Wait, when is Mother's Day again? Did I buy Mom a card?" Below this copy, the simple grid design is both easy to scan and quite visually appealing. Each card picture is a CTA in and of itself -- click on any one of them, and you'll be taken to a purchase page.
