I came across a great article yesterday on MarketingSherpa.com which summarized some very practical and useful tips on improving email opt-ins.  Below are 10 low-cost tactics collected from past MarketingSherpa case studies including how to’s on boosting referrals, establishing co-registration barters, optimizing registration pages and using offline channels for email address collection.

Low-cost Tactics for Opt-in Growth

1.     Increase incentive for referrals - offer a discount coupon to encourage your customers to recruit new opt-ins to their email newsletter and promotional messages

2.     Highlight relevance in co-registration placement - find relevant partners and present your offer in a compelling way

3.     Create co-branded sweepstakes – recruit partners to share the promotion with their own customers and in exchange, trade opt-in checkboxes on one another’s sites.

4.     Combat email address typos – conduct tests to capture email typos before they reach your database

5.     Test a delayed intercept for opt-ins i.e. test a version of on overlay that appears only after your visitor spends 1+ minute on the site.

6.     Test additional locations for opt-in checkboxes i.e. add them on higher traffic web pages

7.     Test small tweaks of registration form such as offer type, images, required fields, amount of information and submit button copy

8.     Use telesales and customer service reps to collect opt-ins – have your inbound call center representatives ask for email opt-ins during calls

9.     Print an opt-in URL on receipts for POS registrations – let customers enter their own information through a custom URL on a sales receipt

10.   Add change-of-email address form to site - place reminders throughout your site that ask customers to report a change of address.
