Email Marketing FAQs
1. Is email marketing even still relevant in 2021?
Yes! If anything, email marketing is even more relevant now. Thanks in part to its expert adaptation to mobile device viewing, email marketing offers one of the biggest ROIs of all of the marketing strategies available to you.
2. I’m worried about my email going to spam. Is there a way to stop this?
This can be a huge concern for business owners. How will your customers see your email if it went into their spam folder? An excellent email marketing agency will know all of the tips and tricks to keep your emails out of the spam folder and get them into your customers’ inboxes.
3. How do I pick the email marketing software that will work best for my company?
This is also something that an agency can help you with but I usually recommend MailChimp for small businesses. It has simplified templates, split testing, and solid automated campaigns.
For medium to large-sized businesses, HubSpot is, hands-down, the best available. A lot of the agencies on this list are HubSpot partners and that just goes to show what an excellent email marketing software they are.
Not only is it user-friendly, but its templates are also reusable and efficient and the split testing capacities are top-notch. They also put a lot of emphasis on teaching and training. They want their users to be completely comfortable with their system.
4. Should I buy an email list?
It’s not recommended. To stay in compliance with CAN-SPAM regulations and stay out of restriction from the major ESP providers, you should utilize the site and social opt-in gateways that obtain approval from your email subscribers.
5. Do you have any statistics to show me how well email marketing works?
Studies have shown that consumers are more likely to click through an email than on a social media post. In fact, some studies estimate that email campaigns are six times more likely to receive attention than a social media campaign!
